Definition of the class
The yield criterion defines the elastic region, the yield surface (where the plasticity occurs) and the impossible region for the stress state function.
The yield criterion needs to know the hardening law considered, which is passed in the constructor.
The yield criterion class main methods are:
Used commonly in the Flow rule:
- CalculateYieldCondition(...)
- CalculateStateFunction(...)
- CalculateDeltaStateFunction(...)
Used to compute the energy dissipation:
- CalculatePlasticDissipation(...)
- CalculateDeltaPlasticDissipation(...)
Used when IMPLEX is active:
- CalculateImplexPlasticDissipation(...)
- CalculateImplexDeltaPlasticDissipation(...)
