Interface Models in Coupled Thermoelasticity
TECHNOLOGIES
Autore/i: Serpilli, Michele; Dumont, Serge; Rizzoni, Raffaella; Lebon, Frédéric
Classificazione: 1 Contributo su Rivista
Abstract: This work proposes new interface conditions between the layers of a three-dimensional composite structure in the framework of coupled thermoelasticity. More precisely, the mechanical behavior of two linear isotropic thermoelastic solids, bonded together by a thin layer, constituted of a linear isotropic thermoelastic material, is studied by means of an asymptotic analysis. After defining a small parameter ε, which tends to zero, associated with the thickness and constitutive coefficients of the intermediate layer, two different limit models and their associated limit problems, the so-called soft and hard thermoelastic interface models, are characterized. The asymptotic expansion method is reviewed by taking into account the effect of higher-order terms and defining a generalized thermoelastic interface law which comprises the above aforementioned models, as presented previously. A numerical example is presented to show the efficiency of the proposed methodology, based on a finite element approach developed previously.

Classificazione: 1 Contributo su Rivista
Abstract: The aim of this research was to investigate the mechanical performance of an earthen massive cladding, recently used for external/internal layers in Platform Frame technology, through an extensive experimental campaign. The masonry is built with extruded unbaked earth blocks and characterized by dovetail horizontally staggered bed joints. The wall is secured to the structural timber studs through 45 degree-angled fir boards sheathing panels, fixed with steel connectors, and finished with an external plaster with an embedded Glass Fibre Reinforced Polymer (GFRP) mesh, wrapping the whole masonry. The influence of the fir board panels and GFRP jacketing on the mechanical behavior of the earth blocks masonry is investigated and compared with the results obtained for the unreinforced configuration (bare wallettes) in (Stazi et al., 2020). The experimental program consisted of compression, diagonal compression and combined shear-compression tests on 18 wallettes. Digital Image Correlation technique was also adopted to investigate the full field strain maps. The results showed that under compression all the samples (with and without reinforcements) behave as a series of independent slender columns, without significant differences among reinforcement type. Both diagonal compression and shear with compression tests revealed the optimal behavior of GFRP plaster reinforcement that increases the strength values and thanks to an effective confinement effect, limits the out-of-plane bending and determines a monolithic response of the wall.

Classificazione: 1 Contributo su Rivista
Abstract: The pa­per deals with the ex­per­i­men­tal and nu­mer­i­cal char­ac­ter­i­za­tion of the in-plane ax­ial and shear me­chan­i­cal be­hav­ior of sprayed in-situ re­in­forced con­crete (RC) sand­wich pan­els, used as struc­tural walls. Ax­ial com­pres­sion tests were car­ried out on spec­i­mens with dif­fer­ent slen­der­ness ra­tios to study their be­hav­ior un­der ax­ial ver­ti­cal loads. While the di­ag­o­nal com­pres­sion test and shear load with con­stant com­pres­sion test were re­spec­tively per­formed on squared pan­els, an­a­lyz­ing their re­sponse to in-plane hor­i­zon­tal lat­eral forces. Ul­ti­mate ax­ial and shear loads have been ex­per­i­men­tally de­ter­mined and the most sig­nif­i­cant load–dis­place­ment di­a­grams have been re­ported. The ob­tained re­sults have been com­pared with other ex­per­i­men­tal cam­paigns on RC sand­wich pan­els and with con­ven­tional RC walls equa­tions, avail­able in codes of prac­tice and lit­er­a­ture. The struc­tural po­ten­tial­i­ties of RC sand­wich pan­els as load-bear­ing and shear walls are high­lighted. The ex­per­i­men­tal in­ves­ti­ga­tion is cor­rob­o­rated by a 3D non­lin­ear fi­nite el­e­ment (FE) nu­mer­i­cal analy­sis, con­sid­er­ing the in­flu­ence of the in­su­la­tion layer, the ef­fi­ciency of steel con­nec­tors, and the in­volved ma­te­r­ial non­lin­ear­i­ties.

Higher order interface conditions for piezoelectric spherical hollow composites: Asymptotic approach and transfer matrix homogenization method
COMPOSITE STRUCTURES
Autore/i: Serpilli, M.; Rizzoni, R.; Dumont, S.; Lebon, F.
Classificazione: 1 Contributo su Rivista
Abstract: The paper describes the mechanical behavior of composites made of piezoelectric spheres in perfect or imperfect contact. The imperfect contact is achieved by interposing piezoelectric thin adhesive layers between the spheres. First, using asymptotic analysis, transmission conditions of imperfect interface equivalent to the behavior of piezoelectric adhesive layers are obtained at order 0 and 1. These transmission conditions are calculated for ”hard” adhesives, i.e. adhesive materials whose electromechanical constants do not rescale with their thickness. Next, under the assumption of spherical symmetry, the transmission conditions are condensed to a general law of imperfect contact, able to simultaneously describe different contact regimes: piezoelectric hard (order 0 and 1) and soft (or spring-type, order 0 and 1) interface conditions, the perfect continuity conditions, and the piezoelectric rigid (Gurtin–Murdoch or membrane-type) conditions. Lastly, following Bufler’s approach, the homogenization problem of a spherical hollow piezoelectric assembly is solved, extending the classical transfer matrix method to take into account the presence of thin adhesive layers described using the proposed transmission conditions of imperfect contact. A simple numerical example is provided, illustrating the correctness and effectiveness of the homogenization approach in describing the electromechanical behavior of spherical piezoelectric assemblies.

Abstract: A new surgical procedure for the treatment of primary bladder neck obstruction with maintenance of anterograde ejaculation is proposed. In place of monolateral or bilateral bladder neck incision, associated with a loss of ejaculation rate of up to 30%, the new surgical procedure consists of laser drilling the bladder neck with a number of holes and without muscle fiber disrup- tion. The effect of this novel procedure has been studied numerically, with a simplified two-dimen- sional numerical model of the internal urethral sphincter, varying the position and the number of holes in the fibrotic region of the urethral tissue. Results show an improvement of the urethral sphincter opening by increasing the number of holes, ranging from about 6% to 16% of recovery. Moreover, a non-aligned position of holes positively influences the opening recovery. The concen- trations of maximum principal strain and stress have been registered in the proximity of the inter- face between the physiologic and diseased sphincter, and in those regions where the radial thick- ness is significantly thinner. The effects on the first five patients have been included in the study, showing improvement in micturition, lower urinary tract symptoms, sustained ejaculatory func- tion, and quality of life.

Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: The paper describes the mechanical behavior of two linear isotropic poroe- lastic solids, bonded together by a thin plate-like layer, constituted by a linear isotropic poroelastic material, by means of an asymptotic analysis. After defining a small parameter ε, which will tend to zero, associated with the thickness and the constitutive coefficients of the intermediate layer, we characterize three different limit models and their associated limit problems, the so-called soft, hard and rigid poroelastic interface models, respectively. Moreover, we identify the non classical transmission conditions at the interface between the two three-dimensional bodies in terms of the jump of the stresses, increment of fluid, pressure and displacements.

Classificazione: 1 Contributo su Rivista
Abstract: The aim of this research is to investigate, through the Digital Image Correlation (DIC) technique, the mechanical performance of a new type of earth masonry, built with extruded blocks and characterized by dovetail horizontally staggered bed joints. The experimental program consists of two levels of investigations: (i) preliminary phase on components, (ii) compression, diagonal compression and combined shear-compression tests on 12 wallettes. Regarding the components, results showed that the mean compressive strength of the earth block was low (3.5 MPa) with respect to traditional bricks and similar to adobe blocks. The dovetail joints were effective in their joining role showing a rather good strength (2.4 MPa) when tested in triplet configuration. Regarding the wallettes, the DIC highlighted failure modes complying with the ones of a traditional masonry under shear, while it showed a ‘‘column behaviour” with vertical sliding under compressive tests. Fragile failures occurred during the diagonal compression test. DIC revealed to be a promising technique to recover the full-field strain and crack maps.

Derivation of Imperfect Interface Laws for Multi-Physic Composites by a Multiscale Approach: Theoretical and Numerical Studies
Developments and Novel Approaches in Biomechanics and Metamaterials. Advanced Structured Materials
Autore/i: Dumont, Serge; Lebon, Frederic; Rizzoni, Raffaella; Serpilli, Michele
Classificazione: 2 Contributo in Volume
Abstract: In the present study, we focus our attention to a specific type of composite, constituted by two media, called the adherents, bonded together with a thin interphase layer, called the adhesive. We assume that the composite constituents are made of different multi-physic materials with highly contrasted constitutive properties. The study considers a generic multi-physic coupling in a very general framework and can be adapted to well-known multi-physic behaviors, such as piezoelectricity, thermo-elasticity, aswell as to multifield microstructural theories, such as micropolar elasticity.

Autore/i: Serpilli, Michele; Rizzoni, Raffaella; Dumont, Serge; Lebon, Frédéric
Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: The paper describes the mechanical behavior of a composite constituted by two solids, bonded by a thin adhesive layer in a general multi-physic framework, by employing the asymptotic expansion technique. After defining a small parameter ε, which will tend to zero, associated with the thickness and the constitutive coefficients of the intermediate layer, we characterize three different limit models and their associated limit problems: the soft interface model, in which the constitutive coefficients depend linearly on ε; the hard interface model, in which the constitutive properties are independent of ε; the rigid interface model, in which they depend on 1/ε. The asymptotic expansion method is reviewed by taking into account the effect of higher order terms and by defining a general multi-physic interface law which comprises the above aforementioned models. Moreover, the FEM implementation of the transmission model is presented through a numerical example.

Classificazione: 1 Contributo su Rivista
Abstract: We investigate some mathematical and numerical methods based on asymptotic expansions for the modeling of bonding interfaces in the presence of linear coupled multiphysic phenomena. After reviewing new recently proposed imperfect contact conditions (Serpilli et al., 2019), we present some numerical examples designed to show the efficiency of the proposed methodology. The examples are framed within two different multiphysic theories, piezoelectricity and thermo-mechanical coupling. The numerical investigations are based on a finite element approach generalizing to multiphysic problems the procedure developed in Dumont et al. (2018).

An experimental and numerical study on CLT panels used as infill shear walls for RC buildings retrofit
CONSTRUCTION AND BUILDING MATERIALS
Autore/i: Stazi, F.; Serpilli, M.; Maracchini, G.; Pavone, A.
Classificazione: 1 Contributo su Rivista
Abstract: Cross Laminated Timber (CLT) has been gaining more and more attention in research and professional fields as a sustainable and promising construction system for mid- and high-rise structures. The need of buildings higher than those usually built with CLT has pushed the research towards the development of innovative hybrid techniques in which steel framed structures incorporate CLT shear walls. This concept may be potentially extended to existing RC framed buildings, where CLT infill shear walls may constitute the base of an integrated seismic and energy retrofit. In order to investigate this potentiality, this paper presents a preliminary experimental and numerical study focused on the mechanical behavior of CLT panels used as a bracing system. In particular, diagonal compression tests on 3-ply panels have been carried out, also by reproducing a direct load transmission from the RC frame to the CLT infill. A comparison with the results of similar tests on CLT panels (with a different number of layers and thickness) and with unstrengthened and strengthened masonry infill walls has been also provided. In addition, numerical simulations have been carried out, in order to evaluate the changes in RC frame lateral response when CLT infills are added. The results have proved that CLT infills may be used as a strengthening solution, allowing RC frame to reach higher lateral stiffness and peak load values respect to masonry infills.

Abstract: The paper deals with the derivation of non classical interface conditions in linear poroelasticity in the framework of the quasi-static diphasic Biot’s model. More precisely, we analyze the mechanical behavior of two linear isotropic poroelastic solids, bonded together by a thin layer, constituted by a linear isotropic poroelastic material, by means of an asymptotic analysis. After defining a small parameter ε, which will tend to zero, associated with the thickness and the constitutive coefficients of the intermediate layer, we characterize three different limit models and their associated limit problems, the so-called soft, hard and rigid poroelastic interface models, respectively. First and higher order interface models are derived. Moreover, we identify the non classical transmission conditions at the interface between the two three-dimensional bodies in terms of the jump of the stresses, specific discharge, pressure and displacements.

Abstract: In recent years, Italy has been hit by earthquakes, causing significant damage to masonry and reinforced concrete (RC) structures. Especially, common buildings and ordinary structures in many small historical towns of Italian central regions, such as Marche, have suffered dramatic consequences and destruction. Dynamic analysis and seismic structural safety are important topics in civil engineering, which have been studied and deepened for many years by the researchers of the Structural Division of the Department of Civil and Building Engineering, and Architecture of UnivPM. The researches have been oriented towards the investigation of structures under seismic loads in order to improve the knowledge of the structural response under high actions, due to the soil dynamic movements and, thus, define adequate techniques to strengthen the damaged structures. In this paper we present a wide spectrum of main results of our research group, comprising experimental studies, vulnerability analysis and assessment of existing structures, new methods of modelling and theoretical approaches to define the dynamic behavior of structures, also in presence of damage. Finally, we show and discuss new prospects of research for safety, employing advanced techniques and materials to prevent collapse and/or relevant damages in structures.

The results of this research have demonstrated that CLT panels has a higher strength and stiffness if confined. Then, the confinement effect provided by the RC frame on the infill should be accurately considered in the strengthening design.

Classificazione: 1 Contributo su Rivista
Abstract: This paper is concerned with the formal deduction of piezoelectric plate models in microstretch elasticity, by means of an asymptotic analysis with respect to a small parameter ε, being the thickness of the plate. Two different boundary conditions pertaining to electric quantities are considered, leading to two different models: the sensor model and the actuator model, respectively. Each of the two plate problems turns out to be decoupled into a bending problem and a certain microstretch membrane problem, partially coupled with the electric behavior.

After defining a small parameter ε, which will tend to zero, associated with the thickness and the constitutive coefficients of the intermediate layer, we characterize two different limit models and their associated limit problems, the so-called weak and strong micropolar interface models, respectively. Moreover, we identify the nonclassical transmission conditions at the interface between the two three-dimensional bodies in terms of the increases in the stresses, coupling stresses, displacements, and microrotations. Finally, we prove that the solution of the original problems strongly converges toward the solution of the limit problems, as ε tends to zero.

Classificazione: 1 Contributo su Rivista
Abstract: We present an asymptotic two-dimensional plate model for linear magneto-electro-thermo-elastic sensors and actuators, under the hypotheses of anisotropy and homogeneity. Four different boundary conditions pertaining to electromagnetic quantities are considered, leading to four different models: the sensor–actuator model, the actuator–sensor model, the actuator model and the sensor model. We validate the obtained two-dimensional models by proving weak convergence results. Each of the four plate problems turns out to be decoupled into a flexural problem, involving the transversal displacement of the plate, and a certain partially or totally coupled membrane problem.

Abstract: We give an overview of the possible asymptotic models for a layered plate with soft adhesive. More specifically, we study the mechanical behavior of an anisotropic nonhomogeneous linearly elastic three-layer plate with soft adhesive, including the inertia forces, by means of the asymptotic expansion method. By defining a small parameter ε, associated with the size and the stiffness of the intermediate layer, we derive various limit models and their corresponding limit problems, by varying the thickness and rigidity ratios of the adherents and the adhesive layers.

Moreover, we identify the non classical electromechanical transmission conditions at the interface between the two three-dimensional bodies.

Abstract: At a first glance asymptotic expansions and domain decomposition are two alternatives to efficiently solve multi scale elasticity problems. In this paper we will combine these two methods: we will use, for several types of problems, asymptotic expansions and show that for an efficient implementation of problems obtained at the asymptotic limit it may be useful to use domain decomposition type algorithms.

Abstract: In this paper we derive a strain gradient plate model from the three-dimensional equations of strain gradient linearized elasticity. The deduction is based on the asymptotic analysis with respect of a small real parameter being the thickness of the elastic body we consider. The body is constituted by a second gradient isotropic linearly elastic material. The obtained model is recognized as a strain gradient Reissner-Mindlin plate model. We also provide a mathematical justification of the obtained plate model by means of a variational weak convergence result.

Abstract: We study the linear dynamics of a layered elastic beam by means of the asymptotic expansion method. The beam consists of three linearly elastic isotropic layers: the middle layer is considered to be thinner and softer than the upper and lower ones. We characterize the limit models by distinguishing three cases of natural frequencies: the low frequencies associated with flexural vibrations, the mean frequencies associated with axial vibrations and the high frequencies, associated with transversal shear and pinching vibrations.

Abstract: We study the problem of an elastic shell-like inclusion with high rigidity in a three-dimensional domain by means of the asymptotic expansion method. The analysis is carried out in a general framework of curvilinear coordinates. After defining a small real adimensional parameter ε, we characterize the limit problems when the rigidity of the inclusion has order of magnitude 1/ε and 1/ε^3 with respect to the rigidities of the surrounding bodies. Moreover, we prove the strong convergence of the solution of the initial three-dimensional problem towards the solution of the simplified limit problem.

Cesàro-Volterra path integral formula on a surface
MATHEMATICAL MODELS AND METHODS IN APPLIED SCIENCES
Autore/i: Ciarlet, P.G.; Gratie, L.; Serpilli, M.
Classificazione: 1 Contributo su Rivista
Abstract: If a symmetric matrix field e = (eij ) of order three satisfies the Saint-Venant compati- bility relations in a simply-connected open subset Ω of R3, then e is the linearized strain tensor field of a displacement field v of Ω, i.e. e = 1 (∇vT + ∇v) in Ω. A classical 2 result, due to Ces`aro and Volterra, asserts that, if the field e is smooth, the unknown displacement field v(x) at any point x ∈ Ω can be explicitly written as a path integral inside Ω with endpoint x, and whose integrand is an explicit function of the functions eij and their derivatives. Now let ω be a simply-connected open subset in R2 and let θ : ω → R3 be a smooth immersion. If two symmetric matrix fields (γαβ) and (ραβ) of order two satisfy appropriate compatibility relations in ω, then (γαβ ) and (ραβ ) are the linearized change of metric and change of curvature tensor field corresponding to a displacement vector field η of the surface θ(ω). We show here that a “Ces`aro–Volterra path integral formula on a surface” likewise holds when the fields (γαβ) and (ραβ) are smooth. This means that the displacement vector η(y) at any point θ(y), y ∈ ω, of the surface θ(ω) can be explicitly computed as a path integral inside ω with endpoint y, and whose integrand is an explicit function of the functions γαβ and ραβ and their covariant derivatives.

Limit models in the analysis of three different layered elastic strips
EUROPEAN JOURNAL OF MECHANICS. A, SOLIDS
Autore/i: Serpilli, M.; Lenci, S.
Classificazione: 1 Contributo su Rivista
Abstract: The mechanical behavior of three types of laminated strips is investigated. They are made of three layers filled with homogeneous, isotropic and elastic materials; the upper and lower layer are called adherents, the middle layer is called adhesive. The first model studies a strip consisting of three layers made of materials with similar stiffness; the second one concerns with a strip in which the adhesive is soft; in particular, we suppose that the elastic stiffness of the middle layer is two orders of magnitude smaller than that of the upper and lower layers; the third case is a strip in which the core is thinner and stiffer than the two adherents: the elastic modula of the adherents are one order of magnitude bigger that those of the adhesive. After identifying a parameter of smallness ε (which measures the thickness and the stiffness of each layer), the limit of the solution when ε tends to zero has been considered. Afterwards, it has been shown that each solution of the simplified models verifies the so-called limit problems, written using a “weak” and a “strong” formulation. The existence and uniqueness of the solutions of each limit problem have been established. The strong convergence of the exact solutions towards the solution of the limit problem of the first model has been established, too.

Abstract: We study the problem of an elastic inclusion with high rigidity in a 3D domain. First we consider an inclusion with a plate-like geometry and then in the more general framework of curvilinear coordinates, an inclusion with a shell-like geometry. We compare our formal models to those obtained by Chapelle–Ferent and by Bessoud et al.

This formal deduction is purely geometrical because we do not use any information coming from the loading or the constitutive behavior.
