Investigation into the Effects of Weapon Setback on Various Materials and Geometries.

Abstract

The objective of this task was to develop a method for estimating the mechanical behavior of various materials when subjected to weapon (e.g., howitzer) setback forces. A mathematical model was developed for predicting the dynamic mechanical behavior of the materials, from which predictions concerning certain material-geometry combinations were made. Tests were carried out with aluminum and steel specimens and the resultant data compared with results predicted by the mathematical model. The mathematical model selected was a viscoelastic model involving viscous, elastic, and in one instance, plastic parameters. This model accurately predicted the measured values in five material-geometry combinations actually tested. The methodology described in this report can be used to predict accurately the structural integrity of munition components when exposed to weapon setback environments.
