摘要：
A numerical method is proposed to predict the failure of mechanical structures. It is based on the generalization of the classical static shakedown theorem to damaged inelastic structures. Ductile plastic damage is taken into account by using the models of Lemaitre and Shichun-Hua. The obtained results are compared in the special case of limit analysis to those obtained by incremental methods. (C) 1998 Elsevier Science S.A. All rights reserved.
