The problem of loss stability and post-critical behavior a compressed orthotropic rectangular plate on nonlinearly elastic base containing continuously distributed fields dislocations disclinations under the influence small normal load is considered. compressive force components are evenly along edges act parallel to main directions elasticity. formulated as an analogue system nonlinear Karman ...

A contact/friction isoparametric finite element for the analysis of connections between laminated composite plates is presented. The element is compatible with a three-dimensional plate element based on layer-wise constant shear theory. The contact/friction element is based on a simple regularization of the unilateral contact with an orthotropic Coulomb friction problem. Two different friction ...
