Abstract
A posteriori error estimators based on constitutive relation residuals are developed to measure the quality of finite element computations of structur es which exhibit plastic/viscoplastic behaviour with softening. All the cla ssical error sources involved in the computation over the studied time inte rval are taken into account: the space discretization (the mesh), the time discretization and the iterative technique used to solve the non-linear dis crete problem.
