Abstract
A constitutive framework for large elastoplastic deformations is brief ly presented, along the lines of Mandel's theory, in a form most appro priate for computational convenience. A general purpose stress-point a lgorithm is adapted to the present large deformation framework. An acc uracy analysis is carried out and the performances of several variants are compared, particularly those related to the anisotropic intensity and plastic spin in reference to two specific anisotropic models. The effect of elastic deformations on the overall response is demonstrate d for special loading paths.
