DEVELOPMENT OF EXPERIMENTAL STRESS ANALYSIS METHODS TO DETERMINE STRESSES AND STRAINS IN SOLID PROPELLANT GRAINS. A MODIFIED METHOD OF HOLOGRAPHIC INTERFEROMETRY FOR STATIC AND DYNAMIC PHOTOELASTICITY.

Abstract

A simplified absolute retardation approach to photoelastic analysis is described as an alternative to the more commonly used relative retardation approach. Isochromatics and isopachics are presented as applications of the method to static and dynamic problems. (Author)
