| Abstract: | The linear relation between the acoustic emission(AE) cumulative energy and the crack propagation of the composite solid propellant was deduced in this paper.The damage evolutional modal described by the AE cumulative energy was established.The results of a uniaxial loaded AE experiment showed that this evolutional modal was correct,which could be used for studying the damage for the composite solid propellant. |
