Parameters
----------
table
A sequence of sequences of Floats specifying the items described below.
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.
extrapolation
A SymbolicConstant specifying the extrapolation method for the yield stress with respect
to the equivalent plastic strain. This argument is valid only if hardening=ISOTROPIC.
Possible values are CONSTANT and LINEAR . The default value is CONSTANT.
