Materials and Contact Characterisation IX
Spallation in ductile metals is often dominated by nucleation, growth and coalescence of voids. Previous research clearly shows that the volume density of nucleated voids is closely related to many factors such as grain size, loading condition and the like. In addition, it is confirmed that the nucleation of voids is inhibited by the existing voids with the plastic region around them. Therefore, a new model of dynamic damage is proposed, where the void nucleation equation is coupled withdoi:10.2495/mc190231 fatcat:3gybwxh3xndprk5wrfam7ahvfe
