DOI: 10.1016/j.ijsolstr.2017.07.012
Abstract: Abstract Most cohesive zone models for the simulation of crack growth in ductile metals do not reflect continuum constitutive laws on traction–separation relationships across cohesive crack surfaces. In this study, a continuously-deforming material layer associated… read more here.
