“…The mechanical properties of this layer are obtained by applying an asymptotic limit analysis procedure (Lebon and Ronel-Idrissi, 2007;Lebon et al, 1998Lebon et al, , 2004. For this purpose, it is proposed first to obtain the mechanical properties of the 3-D material obtained by homogenizing those of brick and mortar.…”

This article is aimed at proposing a new development of a layer-wise 2D finite-element method for multilayers considering the laminated plate as a superposition of Reissner plates coupled by interfacial stresses. Here, despite the 2D description of the laminates, the interfaces show a particular behavior, elastic or elastoplastic (Von-Mises criterion). The finite element formulation is derived and an eight-node multiparticle element is detailed. The application example of a double lap joint with an elastoplastic adhesive is then considered. The adhesive layer is modeled as an interface. The loading scheme is a load-unload-load one. Interface shear and normal stresses are compared to 3D finite element results. A good agreement between both techniques is observed, particularly for the prediction of the history of the slip between the two adherends and the plastic strains in the adhesive.

“…in Klarbring (1991), Abdelmoula et al (1998) and Geymonat et al (1999). In this framework, ''soft'' and ''hard'' interface models have been derived (Lebon et al, 2004;Lebon and Rizzoni, 2010), even considering nonlinear constitutive laws. Moreover, first order and second order theories have been obtained considering the terms at zero order and at first order of the asymptotic expansion, respectively.…”

a b s t r a c tThe present work deals with the formulation of a kinematic enriched model for cohesive interface. In fact, the interface kinematics is defined by the relative displacement occurring between the two surfaces of the interface and, even, by the strain arising in the plane of the interface. A damage model which accounts for the mode I and mode II and for the axial deformation of the interface is proposed starting from the Drucker-Prager failure criterion. A numerical procedure is developed implementing the proposed interface model into a new finite element. The nonlinear evolutive problem is solved adopting a predictorcorrector technique within the backward time integration scheme. Simple numerical simulations are presented in order to assess the features of the model. Moreover, numerical applications are carried out in order to demonstrate the ability of the proposed model in reproducing the mechanical behavior of the cohesive elements strengthened with external FRP reinforcements. Comparisons between available experimental data and numerical results obtained using the proposed model show the effectiveness of the presented formulation.
