Abstract
A numerical method is proposed to predict the failure of mechanical st ructures. It is based on the generalization of the classical static sh akedown theorem to damaged inelastic structures. Ductile plastic damag e is taken into account by using the models of Lemaitre and Shichun-Hu a. The obtained results are compared in the special case of limit anal ysis to those obtained by incremental methods. (C) 1998 Elsevier Scien ce S.A. All rights reserved.
