摘要
Abstract
By the cyclic tensile test of composite solid propellant under different stress, the change rules of cyclic tensile curve, characteristic strain and dissipated energy in the process of loading were found, and the damage characteristic of composite solid propellant was analyzed. The results showed that the change rules of dissipated energy in the process of cyclic tension reflected the different damage mode of the propellant at different tensile strain, the main portion of the dissipated energy was supplied by the matrix, and the amplitude of stress and the logarithm of the cyclic tensile life had good linear relation.关键词
