Creating Nodes to Nodes Connection Properties

A nodes to nodes connection property defines the degrees of freedom of a points to points analysis connection. The connection can be rigid or coincident. However, in both cases Abaqus models the connection using rigid CARDAN and CARTESIAN connectors with selected degrees of freedom constrained using connector motion. See Connection-type library in the Abaqus Elements Guide for more information. You can request history output of relative displacements and rotations and of total, elastic, viscous, and reaction forces and moments from a nodes to nodes connection property. The support for the history output request is the connection mesh.

This task shows you how to create a nodes to nodes connection property between two parts.

  1. Click the Nodes to Nodes Connection Property icon .

    The Nodes to Nodes Connection Property dialog box appears, and a Nodes to Nodes Connection Property object appears in the specification tree under the Properties objects set.

  2. You can change the identifier of the nodes to nodes connection property by editing the Name field.

  3. In the specification tree, select a Points to Points Analysis Connection object created previously in the Nonlinear Structural Analysis workbench.

    The Supports field is updated to reflect your selection.

  4. Select either type of connection. Abaqus for CATIA V5 treats Rigid and Coincidence connectors identically.

  5. By default, nodes to nodes connection properties constrain all degrees of freedom and are associated with the global, rectangular Cartesian axis system. To change the default behavior, click the Component Editor icon and do the following from the Definition dialog box that appears:

    1. Toggle off the degrees of freedom from which you want to remove the connection property.

    2. Specify a local coordinate system for the degrees of freedom. Local coordinate systems are defined in the CATIA Part Design workbench.

    3. Click OK to accept your changes and to close the Definition dialog box.

  6. Click OK in the Nodes to Nodes Connection Property dialog box.
