*RATE DEPENDENT
Data lines to define the overstress powerlaw parameters (TYPE=POWER LAW):
First line:
1. D.
2. n.
3. Temperature.
4. Firstfield variable.
5. Second field variable.
6. Etc.,uptofivefieldvariables.
Subsequent lines (only needed if the DEPENDENCIES parameter has a value greaterthan five):
1. Sixthfield variable.
2. Etc.,up to eight field variables per line.
Repeat this set of data lines as oftenas necessar y to define the dependence of themater ialparameters
on temperature and other field variables.
Data line to define the Johnson-Cook rate parameters(TYPE=JOHNSON COOK):
First (and only) line:
1. C.
2. .
Data lines to define yield stress ratios (TYPE=YIELDRATIO):
First line:
1. Yieldstress ratio, .
2. Equivalentplastic strain rate, (or , the absolute value of the axial plastic s train rate
in uniaxial compression, for the crushablefoam m odel).
3. Temperature.
4. Firstfield variable.
5. Second field variable.
6. Etc.,uptofivefieldvariables.
Subsequent lines (only needed if the DEPENDENCIES parameter has a value greaterthan five):
1. Sixthfield 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 the yield stress ratio on
equivalent plastic strain and, ifneeded, on temperature and other predefined field variables.
