APPLICATIONS OF NON-LINEAR VISCOELASTICITY AND CUMULATIVE DAMAGE (A REALISTIC EVALUATION OF REAL PROPELLANT BEHAVIOR)

Abstract

A study was undertaken to provide a realistic evaluation of real propellant behaviors, with emphasis upon the effects of larger strains and their attendant marked nonlinear viscoelastic behavior. To accomplish this primary objective, efforts were made to: (1) evaluate the nonlinear viscoelastic response properties of solid propellants in terms of the theories of Farris, and reduce to practice the associated analytical methods; and (2) develop a practical, empirical method of calculating cumulative damage in terms of a strain failure criterion.
