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