Molecular dynamics study of interfacial cohesive zone law: Elastic Constant Effects

Zhou, X.W.; Moody, Neville R.; Jones, Reese E.; Zimmerman, Jonathan A.; Reedy, Earl D.

A cohesive zone, finite element fracture analysis is based upon a traction-separation relation. Our recent work has used molecular dynamics simulations to derive general traction-separation relationships for interfacial fracture between two brittle materials under mix-mode loading conditions. Here we apply our method to explore the effects of elastic constants of the two materials on the traction-separation relationship. A comparison and discussion of our results will be provided.
