摘要：

A general resultant stress plasticity algorithm called global plasticity, based on Ilyushin's criterion, is proposed for shell elements. The resultant stress calculation algorithm is developed for an elastoplastic, orthotropic. material. The proposed algorithm is then implemented and validated in the RADIOSS explicit program for metal forming problems. (C) 2001 Elsevier Science Ltd. All rights reserved.
