Abstract
The incremental FE method, which is a widely used procedure for the solution of problems of elasto-plasticity, is considered in this paper. An adaptive variant of this method is described as a tool for efficient computation of sufficiently accurate approximate solution. The main investigation is then devoted to the use of composite FE grids within the incremental FE methods. The attention is devoted mainly to implementation and convergence analysis of the Newton–FAC/BEPS iterative procedures for the solution of nonlinear systems arising withinthe load steps.
