*JOINTED MATERIAL
10.4 *JOINTED MATERIAL: Specify the jointed material model.
This option is used to define a failure surface and the flow parameters for a single joint system or for bulk
material failure in the elastic-plastic model of a jointed material, or it can be used to define shear retention in
open joints. Up to three joint systems can be defined for each material point.

Optional parameters:
DEPENDENCIES
Set this parameter equal to the number of field variable dependencies included in the definition of
the parameters of the model, in addition to temperature. If this parameter is omitted, it is assumed
that the parameters depend only on temperature. See “Specifying field variable dependence” in
“Material data definition,” Section 16.1.2 of the ABAQUS Analysis User’s Manual, for more
information.
JOINT DIRECTION
Set this parameter equal to the name of the *ORIENTATION used to define the direction of a joint
system. This use of the *ORIENTATION option does not affect the output of components of stress
and strain—it only defines the joint orientation in the original configuration. Omit this parameter to
give the bulk material failure parameters. The JOINT DIRECTION parameter cannot be used with
the SHEAR RETENTION parameter.
NO SEPARATION
Include this parameter to prevent the joint from opening. This parameter must be used in conjunction
with the JOINT DIRECTION parameter.
SHEAR RETENTION
Include this parameter to define shear retention in open joints. If this parameter is omitted, zero
shear retention is assumed. The SHEAR RETENTION parameter cannot be used with the JOINT
DIRECTION parameter.
