*PLASTIC:

Specify a metal plasticity model.

This option is used to specify the plastic part of the material model for elastic-plastic materials that use the
Mises or Hill yield surface.

Products:

ABAQUS/Standard

ABAQUS/Explicit

Type:

Optional parameter:

HARDENING

Set HARDENING=ISOTROPIC (default) to specify isotropic hardening.

Set HARDENING=KINEMATIC to specify linear kinematic hardening.
Set HARDENING=COMBINED to specify nonlinear isotropic/kinematic hardening.
Set HARDENING=JOHNSON COOK to specify Johnson-Cook hardening in an

ABAQUS/Explicit analysis.

Set HARDENING=USER to define isotropic hardening in user subroutine UHARD in an

ABAQUS/Standard analysis.

Optional parameter for use with HARDENING=ISOTROPIC or HARDENING=COMBINED:

DEPENDENCIES

Set this parameter equal to the number of field variable dependencies included in the definition
of hardening behavior, in addition to temperature and possibly strain range. If this parameter is
omitted, the hardening behavior does not depend on field variables. See “Specifying field variable
dependence” in “Material data definition,” Section 16.1.2 of the ABAQUS Analysis User’s Manual,
for more information.
