Examples of defining general contact interactions (Abaqus)

Example: Contact inclusions and property assignments

In this example of an Abaqus Structural analysis, a model contains three General Contact simulation objects, each specifying the surfaces to include.

Each General Contact simulation object defines unique contact properties through General Contact Property modeling objects, which in turn define the properties through three Surface Interaction modeling objects.

General contact	Surfaces	Contact properties	Surface interaction
General Contact1	Surface pair Region1 and Region2	General Contact Property1	Surface Interaction1
General Contact2	Self-contact of surface Region3	General Contact Property2	Surface Interaction2
General Contact3	Contact between surface Region4 and the Default All-Inclusive Surface	General Contact Property3	Surface Interaction3

The model also assigns unique contact properties to the general contact domain and to a set of surfaces using two Contact Assignment modeling objects.

Contact Assignment modeling object	Surfaces	Surface interaction
Contact Property Assignment1	General contact domain	Surface Interaction1
Contact Property Assignment2	Surfaces Region5 and Region6	Surface Interaction3

The example uses the Contact Property Assignment option on the Solution Control page of the Solution dialog box to create the objects and the Modeling Objects Manager to specify the assignment of the properties during the Simulation.

Example: Defining both general contacts and contact pairs in the same simulation

You can model contact using both the general contact and the contact pair methods in the same model and share modeling objects, such as a Surface Interaction modeling object.

In this example, a General Contact simulation object models the contact between Region7 and Region8, and a Surface-to-Surface simulation object models the contact between Region9 and Region10. Both interactions define their contact properties using the same Simulation Interaction modeling object, Surface Interaction5.

General contact	Surfaces	Contact properties	Surface interaction
General Contact7	Surface pair Region7 and Region8	General Contact Property1	Surface Interaction5
Surface to Surface2	Surface pair Region9 and Region10	General Contact Property2	Surface Interaction5
