Atomistic Potential Based Cohesive Modeling for Surface Separation

An atomistic potential based (AP-based) cohesive modeling methodology is briefly presented. For this purpose, pair potentials and and multi-body potential such as EAM are considered and their softening characteristics are shown. Based on the AP-based hyperela- sicity with softening mechanism, the cohesive law in terms of cohesive traction and separation displacement is obtained. The presented method is feasible and a few remarks are given.
