THEORETICAL AND EXPERIMENTAL STUDY OF LOW-VELOCITY PENETRATION PHENOMENA

Abstract

The tensor formulation of the stress-strain relationships involved in finite time-dependent deformation of a solid has been changed from that previously reported. The new mathematical model is described along with a discussion of the applicable mathematics. The computer code developed to calculate the flow field in impact has been modified to eliminate propagated error in the time dimension. A system for high speed photographic analysis of deformation of wires and rods is described. Data from rod-to-rod impact are analyzed to determine the energies involved in metal deformation. Average energy per unit deformation is found to decrease with increasing impact velocity.
