In this work, a new strategy to integrate stress without an iterative root-finding process is introduced using a generalized form of the effective plastic strain increment for the purpose of reducing the computational cost of FE-simulations where advanced theoretical plasticity models are implemented. The accuracy and robustness of the method are validated through material anisotropy prediction at a variety of time increments by implementing anisotropic yield functions into the finite element framework. The results of the current method are compared to that of the Euler backward and analytical methods. Moreover, the earing prediction quality after a cup drawing FE-simulation and the associated computational efficiency are comparatively studied.
