[CIG-SHORT] plastic strain

[Charles Williams]

Hi Birendra,

1.  total_strain is equal to elastic_strain + plastic_strain.  Look in the manual chapter on material models to see how things are set up.
2.  Strain always honors boundary conditions; however, you can get cases where the total strain is zero, but there is still plastic strain (e.g., elastic and plastic strains could cancel under certain conditions).

Cheers,
Charles
