Influence of Stress, Strain and Strain Rate on Dynamic Fracture.

Abstract

The work presented in this report summarizes the results obtained from an examination of dynamic fracture in aluminum alloys under biaxial strain conditions. It is shown that the initiation of dynamic fracture is controlled by the maximum principal stress and the pulse duration. The geometry of the fracture surface is explained in terms of the nucleation of microcracks, and the extent of the fracture is strongly dependent on the aging treatment undergone by the alloy.
