✦ Synopsis

In order to perform eective and reliable computations for thin walled problems in ®nite plasticity, a central goal is to discretize a structure by minimizing the degrees of freedom while controlling the numerical error. In this paper an h-adaptive procedure for shell problems in ®nite plasticity is presented. An error indicator for ®nite plasticity is derived on the basis of the Superconvergent Patch Recovery (SPR) procedure and combined with components of shell element analysis, mesh generation and inter-mesh projection technique. Numerical examples are given illustrating the eectiveness of the combined approach.

The purpose of this paper is to present an adaptive finite element-boundary element coupling method for elasto-plastic analysis. The finite element method is utilized in regions where plastic material behavior is expected to develop, whereas substantial parts of the bounded/unbounded linear elastic
