A finite element analysis of elasto-plastic Reissner-Mindlin plates
is presented. The discrete field equations are derived from a nonlinear
version of the Hu-Washizu variational principle. Associative plasticity,
including linear hardening, is
employed by means of a generalized von Mises-type yield function.
A predictor/corrector scheme is used to integrate the plastic
constitutive rate equations. Numerical simulations are conducted
for a series of test problems to illustrate performance of the formulation.
