Abstract
This work concerns the rate independent behavior for metals at large strain. It develops a theoretical study on forming limit diagram, using the two three-dimensional approach proposed by Rice and Cordobois Ladvez. In this context the critical strain are analysed in the phenomenological models framework. The model is presented:
-
The isotropic case, with Von Mises isotropic yield function, for which the comparison of instability criteria is presented in terms of the hardening parameters. It was showed that the predicted forming limit diagram was strongly influenced by the type of hardening law and the instability criteria.
