Abstract
Two- and three-dimensional photoelasticity methods to stress and strain analyze propellant-grain models are reviewed. Pressure, restrained shrinkage and transient thermal loadings are considered. The advantages and limitations of two-dimensional simulations of the three-dimensional problems are studied in detail.
