The table data for this object are:
- If *type*=POWER_LAW, the table data specify the following:
- D.
- n.
- Temperature, if the data depend on temperature.
- Value of the first field variable, if the data depend on field variables.
- Value of the second field variable.
- Etc.
- If *type*=YIELD_RATIO, the table data specify the following:
- Yield stress ratio, R=¯σ/σ0.
- Equivalent Plastic strain rate, ˙¯εpl.
- Temperature, if the data depend on temperature.
- Value of the first field variable, if the data depend on field variables.
- Value of the second field variable.
- Etc.
- If *type*=JOHNSON_COOK, the table data specify the following:
- C.
- ˙ε0.
