Abstract

Abstract

The expanding gap-ring test was put forward and designed for studying the evolvement of damage in material under impact tensile. The impact tensile process of an expanding gap ring was studied by numerical simulation. The length of loading time for different positions in the gap ring is relative to the distances of these positions from the gap. However, the length of time cant be calculated by Mott-wave transmitting, but can be determined by the velocity histories of nodes in different positions of the gap ring.
