A return mapping algorithm for isotropic and anisotropic plasticity models using a line search method
The numerical integration of constitutive models in computational solid mechanics codes allows for the solution of boundary value problems involving complex material behavior. Metal plasticity models, in particular, have been instrumental in the development of these codes. Here, most plasticity models implemented in computational codes use an isotropic von Mises yield surface. The von Mises, of J2, yield surface has a simple predictor-corrector algorithm - the radial return algorithm - to integrate the model.
