The von Mises Model and Its Integration
Among the many rate-independent, elasto-plastic constitutive laws available today for describing the stress–strain behavior of materials, the models employing the von Mises yield surface, and the associated flow rule are some of the widely used and simplest. While isotropic hardening models are generally adequate for monotonic loading applications, more sophisticated models (e.g., nonlinear kinematic hardening models, multi-surface models, bounding surface models, etc.) are generally needed for cyclic loading applications.
