These objects define connections between parts or bodies. The objects are grouped by functionality.
| Object | Description |
|---|---|
| Beam | Defines a structural element that carries a load primarily in bending. |
| Bearing | Defines a two-dimensional elastic element used to confine relative motion and rotation of a rotating part. |
| Body Interactions | Sets global options for all Body Interaction objects in an Explicit Dynamics Analysis. |
| Body Interaction | Creates contact between bodies in an Explicit Dynamics Analysis. |
| Connections | Defines connections between two or more parts or bodies. |
| Connection Group | Defines connections among selected bodies. |
| Contact Region | Defines conditions for individual contact and target pairs. |
| End Release | Allows specified degrees of freedom to be released on a vertex between line bodies or a node between beam (line body) elements. |
| Interstage | Connects the faces of the cyclically symmetric bodies specified by two different Stage objects. |
| Joint | Defines conditions for reference and mobile pairs that make up a joint. |
| Spot Weld | Defines conditions for individual contact and target pairs for a spot weld, which is used to connect individual surface body parts to form a surface body model assembly. |
| Spring | Regains its undeformed shape after a compression or extension load is removed. |
