Evaluation of elastic energy in systems with surface energy needs special care, for besides external forces, there are forces due to molecular attraction that cause elastic deformation and lead to elastic energy storage. 

Elastic energy storage resulting from bond stretching and angle changes.

As will be amplified below, contributions to R arise from the energy actually required to create the new surface (a quantity related to the surface tension), the orientation of chains near the surface, the breaking of chains that spanned the cracking region, and rubber elasticity energy storage effects. 

The interfacial processes that influence adhesion are examined. These are the microscopic processes (wetting, adsorption and charge transfer) and the macroscopic processes (elastic energy storage, the elimination of voids, and dissipation of energy during separation).
