Numerical study of ductile failure under non-proportional loading

This paper investigates two numerical methods for predicting the initiation of ductile failure under moderately and strongly non-proportional loading paths. Two distinct phenomena are considered as indicators for the initiation of ductile failure: (i) the localization of deformation into a narrow ba...
