Required arguments
- table
A sequence of sequences of Floats specifying the items described below.
Optional arguments
- hardening
A SymbolicConstant specifying the type of hardening. Possible values are ISOTROPIC, KINEMATIC, COMBINED, JOHNSON_COOK, and USER. The default value is ISOTROPIC.
- rate
A Boolean specifying whether the data depend on rate. The default value is OFF.
- dataType
A SymbolicConstant specifying the type of combined hardening. This argument is only valid if hardening=COMBINED. Possible values are HALF_CYCLE, PARAMETERS, and STABILIZED. The default value is HALF_CYCLE.
- strainRangeDependency
A Boolean specifying whether the data depend on strain range. This argument is only valid if hardening=COMBINED and dataType=STABILIZED. The default value is OFF.
- numBackstresses
An Int specifying the number of backstresses. This argument is only valid if hardening=COMBINED. The default value is 1.
- temperatureDependency
A Boolean specifying whether the data depend on temperature. The default value is OFF.
- dependencies
An Int specifying the number of field variable dependencies. The default value is 0.
Table data
If hardening=ISOTROPIC, or if hardening=COMBINED and dataType=HALF_CYCLE, the table data specify the following:
Yield stress.
Plastic strain.
Equivalent plastic strain rate, .
Temperature, if the data depend on temperature.
