Abstract

The paper presents the implicit numerical integration by a Generalised Backward Euler algorithm of a mixed isotropic-kinematic hardening model for Structured clays. In the first part the main characteristics of the model are presented. This is followed by the description of the return mapping algorithm which allows the model to be implemented in finite element codes, ensuring numerical accuracy and stability requirements to be satisfied. In the final part of the paper, numerical simulation of single element tests are illustrated.
