There are multiple possible methods for modeling adhesive debonding in finite element simulations. However, many of these techniques are incapable of meeting all of the requirements of a thermomechanical simulation involving assemblies with thin layers of elastomeric potting materials. In this paper, these requirements are first identified, then one particular method, termed the “shim layer” modeling approach, is described. This modeling approach is capable of meeting all of the modeling requirements.
