Abstract
- Stress integration algorithms are formulated for the novel distortional hardening model (HAH).
- A multi-step N-R method is proposed for the gradient and Hessian matrix of the novel hardening model.
- The accuracy in the anisotropy is evaluated by the conventional yield model and the HAH model.
- The accuracy analysis for the distortional hardening model is provided by the iso-error maps.
