Abstract: This report is a review of the developments at the US Army Research Laboratory from 2001 to 2007 in the area of mechanochemistry of damage and its applications in terminal ballistics. It focuses on the radial cracking paradox in terminal ballistics. To justify the ballistic paradox we use two approaches: the sharp interface approach and the narrow damaged zone approach. The sharp interface approach is based on the concepts of tensorial chemical potentials and the stress-driven morphological instabilities. The narrow damaged zone approach is based on the Landaus order parameter concept in which the order parameter describes the fraction of the broken bonds.
