You can define the translational or angular positions at which constitutive forces and moments are zero for the available components of relative motion. Reference lengths/angles are subtracted from the components of relative motion before being used in elasticity and friction behavior. You can define only one reference length option. For more information, see Connector behavior, Section 17.2.1 of the ABAQUS Analysis User's Manual.
To create or edit a reference length:
Display the connector property editor using one of the following methods:
To create a new connector property, follow the procedure outlined in Creating connector properties, Section 15.11.7.
To edit an existing connector property, select ConnectorPropertyManager from the main menu bar, select the connector property from the list that appears, and click Edit.
In the Edit Connector Property dialog box, do one of the following:
To define a new reference length option, click Add and select Reference Length from the option menu that appears.
To edit an existing reference length option, select the option from the Behavior Options list to display the associated data fields for that option.
In the Constitutive Reference Length and Angle portion of the editor, enter the reference lengths and reference angles associated with the available components of relative motion. If you do not enter a value, the reference lengths and reference angles are determined by the initial configuration of the connector.
Select one of the following:
If you want to continue defining behavior options, click Add, select the desired behavior option, and continue the connector property definition. For instructions on defining other behavior options, see Using the connector property editors, Section 15.14.
If you want to view or edit an existing behavior option, select the option from the Behavior Options list. For instructions on editing behavior options, see Using the connector property editors, Section 15.14.
If you want to save your connector property definition and exit the editor, click OK.
