STUDIES OF INTERNAL DISPLACEMENTS IN SOLID PROPELLANT GRAINS. EVALUATION OF PHENOMENOLOGICAL RELATION FOR VISCOELASTIC MATERIALS

Abstract

The purpose of the study presented herein is to demonstrate the applicability of a phenomenolog ical relation between stress, strain rate and temperature in describing the behavior of visco elastic materials, in general, and solid propel lant -particular. The basic relation and its specific equations associated with various test ing conditions are discussed in the appendix. The procedure was to extract from the literature those test data which would not only provide the required material constants, but at the same time permit an evaluation of the relation's range of applicability. Although the majority of the data uncovered left much to be desired in the way of completeness (from the viewpoint of utilization in this evaluation), nevertheless, it was possi ble to detect certain encouraging trends. The manner in which the available data were utilized and the interpretive conclusions are presented.
