How to simplyfy return-mapping algorithms in computational plasticity: Part 1 - Main idea
Original language description
An improved implicit return-mapping scheme for nonsmooth yield surfaces is suggested in this paper. It is based on a subdierential formulation of the ow rule that does not require special treatment at singular points (apices, edges, etc.). Although the ow direction is multivalued in such a case, it is shown that the suggested scheme leads to solving a unique system of nonlinear equations similarly as for smooth yield surfaces. Improved return-mapping schemes of several elastoplastic models containing nonassociative plastic ow rules and nonlinear isotropic hardening laws are introduced together with the corresponding consistent tangent operators.
