This research extends the Gurson model to improve understanding of ductile damage during viscoplastic deformation, suggesting enhanced modeling capabilities.
Gurson model is capable of describing the ductile damage of metals. It is extended to describe the cyclic viscoplastic deformation behavior by incorporating the subloading-overstress model in this article. It is called the extended subloading-overstress-Gurson model.
