DOI: 10.1016/j.ijplas.2020.102836
Abstract: Abstract With elevated confining pressure and low temperatures, geomaterials may exhibit brittle-to-ductile failure transition due to increased cataclastic flow. In this work, we propose a modified phase-field damage model to capture this transition, wherein a… read more here.

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.
