ELASTOPLASTIC ANALYSIS OF PLATE WITH BOUNDARY ELEMENT METHOD

This work is the development of boundary element method for elastoplastic plate analysis to include elastic-linear hardening material. The plate is subjected to bending, in-plane and combined bending and in-plane. The plastic zone is evaluated by using von Mises criterion. The cell discretization is implemented to solve numerically the domain integral caused by plasticity. To evaluate the nonlinear term in the formulation of the boundary element, a total incremental technique is implemented. The capability of the development in this work will be presented by having numerical examples.
