摘要：

The present paper is devoted to the development of a more general code for the prediction of forming limit diagrams (FLDs). For this purpose, the Marciniak-Kuczynski (M-K) theory is treated with a new approach. The code is composed of a main part and several subroutines, which allow the implementation of different hardening laws, yield functions or constitutive equations. The Newton-Raphson numerical method is used to solve the theoretical treatments of localized necking taking into account linear and complex strain paths. (C) 2002 Elsevier Science B.V.
