Gutknecht, Florian; Steinbach, Frank; Clausmeyer, Till; Tekkaya, Erman (CIMNE, 2015)
Open AccessA finite-element simulation of the shear cutting process is used to predict thegeometry of the cutting surface. A fully-coupled Lemaitre-type model is used in the process model for the description of the material behaviour. ...
Comparison of gurson and lemaitre model in the context of blanking simulation of a high strength steel Gutknecht, Florian; Isik, Kerim; Clausmeyer, Till; Tekkaya, Erman (CIMNE, 2017)
Open AccessThe process of blanking takes place in a short band with high accumulated strain undergoing various stress triaxialities. Enhanced implementations for shear and compressive loads of Gurson’s and Lemaitre’s model are directly ...
