5.5.7.2. Contact Debonding Application

Debonding simulations begin by defining contact regions along an interface that will separate. The properties for the contact elements require that the contact Type be Bonded or No Separation contact and that the Formulation is specified as the Augmented Lagrange method or the Pure Penalty method.

The Contact Debonding object specifies the pre-existing contact region (defined using the Connections feature) that you intend to separate and it also references the material properties defined in Engineering Data. You must select the material properties from the Cohesive Zone category with type Separation-Distance based Debonding or Fracture-Energies based Debonding. See the Static Structural & Transient Structural section of the Engineering Data Help for additional information about the Cohesive Zone properties used by this feature.

Apply Contact Debonding

To specify Contact Debonding:

  1. Insert a Fracture folder in the Tree Outline. The Fracture object becomes active by default.

  2. On the Fracture Context Tab: click Contact Debonding. Or, right-click:

    • the Fracture tree object and select Insert>Contact Debonding.

      Or...

    • in the Geometry window and select Insert>Contact Debonding.

  3. Select a Material.

  4. Select a Contact Region.

Tip:  To automatically generate a Contact Debonding object, select a Contact Region and drag and drop it onto the Fracture folder.

Also see the Contact Debonding Object Reference Help page for information about the properties of this feature.
