title = "Computational modelling of interfacial failure",
abstract = "The failure of imperfect bimaterial interfaces is examined. An adhesive relation is prescribed for the interface which governs the normal and shear traction versus normal and shear displacement response. These relations provide, what amounts to, a constitutive law for a thin interface layer which is envisioned to undergo a failure process, when subjected to combined tensile and shear tractions. Based on this model, we examine the effect cracks and flaws as well as on the ductility, toughness, and failure modes of bimaterial interfaces. The deformation of metal matrix composite materials is also investigated. Failure by strain localization in the neighborhood of the inclusion-matrix interface is examined. Both crystal plasticity and J2 flow theory are used to model the plastic deformation of the materials on either side of the interface. In both descriptions, full account is taken of finite changes in geometry, large plastic strains, and material strain rate sensitivity.",
