Abstract

In the present study, with a view to solve the spallation of ductile metal under intense dynamic loading, we develop a new void coalescence criterion accounting for the damage and void geometry based on the geometric relationship between voids. Following the principle of energy conservation, we reveal the physical mechanism explaining the influence of void coalescence on the growth of damage. The comparison between calculated results and experiment data indicates that void coalescence leads to rapid growth of damage, reduction of void numbers, and increase of average void size.
