This option is used to specify the initial yield surface size and, optionally, the post-yield hardening behavior in connector available components of relative motion. It must be used in conjunction with the *CONNECTOR PLASTICITY option.
Products: ABAQUS/Standard ABAQUS/Explicit
Type: Model data
Level: Model
Set this parameter equal to the number of field variable dependencies included in the definition of the connector hardening data, in addition to temperature. If this parameter is omitted, it is assumed that the connector hardening is independent of field variables. See “Specifying field variable dependence” in “Material data definition,” Section 9.1.2 of the ABAQUS Analysis User's Manual, for more information.
Set DEFINITION=EXPONENTIAL LAW to specify the isotropic hardening parameters (Voce model) 
and 
directly. This parameter is valid only for TYPE=ISOTROPIC.
Set DEFINITION=HALF CYCLE (default for TYPE=KINEMATIC) to provide force/moment versus plastic motion data of a first half-cycle. This parameter is valid only for TYPE=KINEMATIC.
Set DEFINITION=PARAMETERS to specify the kinematic hardening parameters 
and 
directly. This parameter is valid only for TYPE=KINEMATIC.
Set DEFINITION=STABILIZED to provide force/moment versus plastic motion data of a stabilized cycle. This parameter is valid only for TYPE=KINEMATIC.
Set DEFINITION=TABULAR (default for TYPE=ISOTROPIC) to provide force/moment versus plastic motion values. Either uniaxial test data or processed data (as explained in “Connector behavior,” Section 17.2.1 of the ABAQUS Analysis User's Manual) from cyclic experiments can be used. This parameter is valid only for TYPE=ISOTROPIC.
Set TYPE=ISOTROPIC (default) to specify the initial yield surface size and, optionally, isotropic hardening data.
Set TYPE=KINEMATIC to specify kinematic hardening data.
