Texture Strengthening of Plates for Ballistic Purposes.

Abstract

Motivated by previous studies in relating texture-based strength to ballistic performance of 5% Ni steel armor, an investigation was initiated to examine other materials, particularly face-centered cubic materials, for possible texture strengthening effects. Theoretical and experimental work were carried out side by side, and significant progress in understanding and achieving that goal are reported here. On the theoretical side, (110) and (111) textures were identified as the most strong contributors to through-thickness strength, and hence ballistic resistance. A computer program to calculate Taylor factors from pole figure data by incorporating spatial crystallite orientation distribution function was developed. Furthermore, theoretical modeling of the ballistic performation process validated the previously speculated effects of normal anisotropy as well as showed the effects of other material properties, including strain hardening and strain-rate sensitivity.
