*TENSILE FAILURE
Set PRESSURE=DUCTILE to model the case where the pressure stress will be limited by the
hydrostatic cutoff stress when the failure criterion is met.
SHEAR
Set SHEAR=BRITTLE to model the case where the deviatoric stresses will be set to zero when the
failure criterion is met.
Set SHEAR=DUCTILE to model the case where the deviatoric stresses will be unaffected
when the failure criterion is met.
Data lines to specify a tensile failure model:
First line:
1. Hydrostatic cutoff stress (positive in tension). (Units of FL
−2
.)
2. Temperature.
3. First field variable.
4. Second field variable.
5. Etc., up to six field variables.
Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than six):
1. Seventh field variable.
2. Etc., up to eight field variables per line.
Repeat this set of data lines as often as necessary to define the dependence of hydrostatic cutoff stress
as a function of temperature and other predefined field variables.
