Detailed Description

This class implements associated Material Status to PerfectlyPlasticMaterial.

This class contains only yield_flag to inform, whether gp is yielding or is in elastic state. temp_yield_flag is used to indicate yield_flag during a process when we try to find a equilibrium state. After This State is reached we update the yield_Flag accordingly. When lastly reached state is equilibrium state we call updateYourself(), so yield_flag containing last reached status of yielding is copied into yield_flag indicating yield status at previously reached equilibrium state.

Tasks:

Storing the yield_flag
Storing the plastic strain + increment.
