DOI: 10.1016/j.engfracmech.2019.106795
Abstract: Abstract The paper deals with new non-proportional biaxial experiments and corresponding numerical simulations to analyze the load-history dependence on damage and fracture behavior of ductile metals. The numerical simulations are based on a phenomenological, thermodynamically… read more here.
