DEVELOPMENT OF EXPERIMENTAL STRESS ANALYSIS METHODS TO DETERMINE STRESSES AND STRAINS IN SOLID PROPELLANT GRAINS. CONSTANT ACCELERATION STRESSES IN A COMPOSITE BODY,

Abstract

The report discusses the experimental stress analysis of composite structures subjected to gravitational forces. The immersion analogy is used to analyze stresses in composite bodies provided all the materials of such bodies have the same weight per unit volume. Applications are described in two-dimensional problems immersing urethane rubber models bonded to epoxy shells in a thallium formate solution. Photoelasticity is used to determine stresses. The method increases the response obtained, and will have application in the solution of problems where constant acceleration stresses are important as in dams and solid propellant rocket grains.
