✦ Synopsis

A formulation for ®nite element plane strain limit analysis of rigidly perfectly plastic solids governed by von Mises' plasticity condition is presented. The approach is based on the kinematic theorem of limit analysis formulated as a minimum problem for a convex and non-smooth dissipation functional. In particular, the mixed 4-node rectangular element presented by Capsoni and Corradi (1997) is reformulated to keep into account isoparametric mapping while ensuring a locking free behaviour and low distortion sensitivity.

We consider the ®nite element (FE) approximation of the Reissner±Mindlin (RM) plate model, and indicate how to design meshes that yield accurate results when the p/hp version of the standard FE method is used. These guidelines allow quantities of engineering interest to be predicted numerically with
