Abstract:

The formulation of the initial stress approach of the boundary element method (BEM) for two-dimensional elastoplastic plates subjected to static tractions is presented. The developed computer code is used to analyze elasto-plastic materials with linear isotropic hardening which satisfy the Huber-Hencky-von Mises yield criterion. Representative volume elements (RVE) containing voids and inclusions are subjected to various boundary conditions. The relation between average stresses and average strains is computed for different volume fraction of voids and inclusions. The results are compared with the solutions computed by the finite element method (FEM). Effective yield stresses and tangent moduli are computed for different materials.
