Résumé : Having established the equations which give the maximum stresses and strains at the inner and outer radii of cylindrical case-bonded grains of infinite length subjected to thermal cycling, the paper discusses the influence of web fraction, case thickness, moduli of elasticity of the case and propellant and of grain Poisson's ratio. It is shown that for modern designs the chamber elasticity can relieve appreciably the thermal stresses and strains. The analysis assumes an ideally elastic behaviour of the propellant and has been developped in the critical case of uniform grain temperature. © 1960.
