A layerwise finite element for multilayers with imperfect interfaces

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