SHEAR FAILURE
Data lines to de fine the failure strain in tabular form (TYPE=TA BULAR):
First line:
1. Equivalent plastic strain at failure, .
2. Rate of equivalent plastic strain, .
3. Dimensionless pressure-deviatoric stress ratio,
.
4. Temperature.
5. First field variable.
6. Second field variable.
7. Etc., up to four field variables.
Subsequent lines (only neede d if the DEPENDENCIES parameter has a value greater than four):
1. Fifth field variable.
2. Etc., up to eight field variables per line.
Repeat this set of data lines as often as nece ssary to define the dependence of strain at failure on plastic
strain, plastic strain rate, stress ratio and, if needed, on temperature and other predefined field variables.
Data line to define the Johnson-Cook shear failure criterion (TYPE=JOHNSON COOK):
First (and only) line:
1. Johnson-Cook failure parameter, .
2. Johnson-Cook failure parameter,
.
3. Johnson-Cook failure parameter,
.
4. Johnson-Cook failure parameter,
.
5. Johnson-Cook failure parameter,
.
