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:
DATA TYPE
Set DATA TYPE=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 DATA TYPE=STABILIZED to specify stress versus plastic strain values of a stabilized
cycle for calibrating the kinematic hardening parameters.
Optional parameter for use with HARDENING=USER:
PROPERTIES
This parameter applies only to ABAQUS/Standard analyses.
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=ISOTROPIC or HARD ENING=COMBINED with DATA TYPE=HALF
CYCLE:
First line:
1. Yield stress.
2. Plastic strain.
3. Temperature.
4. First field variable.
5. Second field variable.
6. Etc.,uptofivefieldvariables.
Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than five):
1. Sixth field 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 var iables.
