To specify predefined friction parameters:

Display the connector property editor by following the procedure outlined in “Defining friction,” Section 15.14.3, and enter the necessary data.

Select Predefined as the Friction model.

Select the Predefined Friction Parameters tabbed page.

Specify the geometric constants and internal contact forces depending on the connection type that you have selected. To display the connection type description that defines the required data entries, see “Connection types,” Section 15.7.1.

To specify internal contact forces:

Display the connector property editor by following the procedure outlined in “Defining friction,” Section 15.14.3, and enter the necessary data.

Select User-defined as the Friction model.

Select the Internal Contact Forces tabbed page.

If desired, toggle on Use independent position components or Use independent motion components and choose the available component of relative position or constitutive motion to be used as an independent variable. Enter the connector relative position or constitutive motion in the direction specified by the independent component in the corresponding field of the table.

If desired, toggle on Use accumulated slip dependence and enter the accumulated slip in the tangent direction in the Accum Slip field of the table.

If desired, toggle on Use temperature-dependent data and enter the temperature.

If desired, specify the Number of field variables and enter the value for the first field variable, the value of the second field variable, etc.

Specify the internal contact force data.
