This option is used to create a surface interaction property definition. The surface interaction properties will govern any contact interactions that reference this surface interaction.

Set this parameter equal to a label that will be used to refer to this surface interaction property.
Use this label on the INTERACTION parameter of the *CONTACT PAIR option (for an Abaqus/Standard contact analysis or an Abaqus/Explicit analysis using the contact pair algorithm) or on the data line of the *CONTACT PROPERTY ASSIGNMENT option (for an Abaqus/Explicit analysis using the general contact algorithm) to assign this surface interaction property to a contact interaction.
This parameter is relevant only when the USER parameter is included.
Set DEPVAR equal to the number of state-dependent variables required for user subroutine UINTER in an Abaqus/Standard analysis or for user subroutine VUINTER or VUINTERACTION in an Abaqus/Explicit analysis. The default is DEPVAR=0.
This parameter applies only to Abaqus/Explicit analyses using the contact pair algorithm.
Set this parameter equal to the thickness of an interfacial layer between the contacting surfaces. The value can be positive or negative.
This parameter is relevant only when the USER parameter is included.
Set this parameter equal to the number of property values needed as data to define the surface interaction model in user subroutine UINTER in an Abaqus/Standard analysis or in user subroutine VUINTER or VUINTERACTION in an Abaqus/Explicit analysis. The default is PROPERTIES=0.
This parameter is ignored when the option is used in association with a connector element.
Set this parameter equal to the thickness that determines the contacting surfaces to be tracked.
In Abaqus/Standard and Abaqus/Explicit the tracking range will be at least as large as the setting of this parameter; an internally computed default will remain in effect if this parameter setting is less than the default. This parameter extends the range over which contact opening distance (COPEN) output is provided for separated surfaces.
In Abaqus/Explicit this parameter also applies if user subroutine VUINTER or VUINTERACTION is in effect. Only contacting surfaces whose proximity is within this thickness are available for user-defined interactions. This parameter affects only node-to-surface contact, and the input value for this parameter cannot be negative. An internal default value is used if a zero value is input or if the parameter is omitted.
This parameter applies only to Abaqus/Standard analyses in which the USER parameter is included.
Include this parameter when the interface stiffness matrix is not symmetric. This parameter causes Abaqus/Standard to use its unsymmetric equation solution procedures.
In an Abaqus/Standard analysis, include this parameter if the surface interaction model is to be defined in user subroutine UINTER
In an Abaqus/Explicit analysis, include this parameter without any assignment if the surface interaction model is to be defined in user subroutine VUINTER. Set USER=INTERACTION if the surface interaction model is to be defined in user subroutine VUINTERACTION. VUINTER is applicable to contact pairs, whereas VUINTERACTION is applicable to general contact.
When this parameter is included, the *SURFACE BEHAVIOR option and its various suboptions cannot be used under the same interaction definition.
First (and only) line:
Out-of-plane thickness of the surface or cross-sectional area for every node in the node-based surface. The default value is 1.0. Abaqus/Standard uses this value to compute the contact nodal areas and contact stresses.
First line:
Out-of-plane thickness of the surface for two-dimensional models or cross-sectional area for every node in the node-based surface. The default value for both is 1.0. In other situations, enter a blank line.
Second line (needed only if the PROPERTIES parameter is used):
Enter the values of the surface interaction properties, eight per line.
Repeat this data line as often as necessary to define all material constants.
