| Abstract: | In this paper, critical bonding crack energy of solid rocket motor propellant/liner was tested through experiments by means of J integral method. Base on analysis of temperature and strain rate influence on crack energy, reference to curve from experiment, material master curve was given out. The result indicated that the effect of temperature (T) is more obvious than that of strain rate(R). |
