Relaxing the multi-stage nested return algorithm for curved yield surfaces and nonlinear hardening laws
Source abstract
Abstract
The multi-stage nested return algorithm is an efficient approach for implementing plasticity and damage models that addresses issues of nonuniqueness and nonconvergence, and which was previously shown to perform well in a variety of verification tests. Straightforward modifications to this algorithm are shown to improve the robustness for high-curvature yield surfaces and nonlinear hardening laws. Improved methods for computing the initial “fast return” are presented with application to two-surface geomodels. These modifications reduce the need for subcycling while maintaining the efficiency of the algorithm.
