Abstract: In present paper, the deformation and the burst strength of solid rocket motor cylinders (SRMC) made of glass-fiber reinforced plastics ( GFRP) are analysed based on the theory of linear film elasticity and the principle of minimum complementary strain energy espeotively,The measurements on deflections and burst pressures of full--size cases and of different size soandard vessels are conformed with the theoretioally calcutlated results very well.
