*PLASTIC
Optional parameter for use with HARDENING=ISOTROPIC:
RATE
Set this parameter equal to the equivalent plastic strain rate, , for which this stress-strain curve
applies.
Optional parameter for use with HARDENING=COMBINED:
DATATYPE
Set DATATYPE=HALF CYCLE (default) to specify stress versus plastic strain values of the first
half-cycle for calibrating the kinematic hardening parameters.
Set DATA TYPE=PARAMETERS to specify the calibrated kinematic hardening material
parameters directly.
Set DATATYPE=STABILIZED to specify stress versus plastic strain values of a stabilized
cycle for calibrating the kinematic hardeningparam eters.
Optional parameter for use with HARDENING=USER:
PROPERTIES
This parameter applies only to ABAQUS/Standard analys es.
Set this parameter equal to the number of property values needed as data in user subroutine
UHARD. The default is PROPERTIES=0.
Data lines for HARDENING=ISOTROPICor HARDENING=COMBINED with DATA TYPE=HALF
CYCLE:
First line:
1. Yield stress.
2. Pl astic strain.
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 yield stress on plastic
strain and, if needed, on temperature and other predefined field variables.
