Assigning cohesive modeling data

In the Property module, you can complete the cohesive modeling data as follows:

  1. Create a cohesive section to define the section properties of adhesive layers at the interface between two bonded parts. You can model a negligibly thin layer of adhesive, a finite-thickness adhesive layer, or a gasket by selecting the constitutive behavior of the cohesive section as Traction Separation, Continuum, or Gasket, respectively. For more information, see Creating cohesive sections.

  2. Define a material for the cohesive region. If you select the Continuum or the Gasket response in the cohesive section editor, you can use the material models available in the Property module to define the continuum material properties. Abaqus/CAE does not support the material models for the Traction Separation response. In this case you must add the material definition using the Keywords Editor, as described in Adding unsupported keywords to your Abaqus/CAE model.

  3. Assign the cohesive section to the cohesive region. For more information, see Assigning a section.
