TENSILE FAILURE
Set PRESSURE=DUCTILE to model the cas e where the pressure stress will be limited by the
hydrostatic cutoff stress when the failure crite rion is met.
SHEAR
Set SHEAR=BRITTLE to m odel 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 specif y 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 D EPENDENCIES 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 o ften as necessary to define the dependence of hydrostatic cutoff stress
as a function of temperature and other predefined fi eld variables.
