Abstract

The paper proposes a robust solution to the stress overshooting problem in bounding surface models. Stress overshooting is one of the main sources of numerical instability in finite element simulations using bounding surface models and has hindered the application of these models in solving large-scale boundary value problems. By proposing a novel framework that can be employed for the models that obey the kinematic hardening law, we provide a robust solution to the overshooting problem. The explicit integration scheme with automatic and adaptive sub-stepping is employed to increase the speed of finite element simulations. The robustness of the solution proposed is demonstrated by several numerical examples.
