| Abstract: | Through AE experiment under stress or strain in uniaxial load conidition at constant speed, the AE characteristics of HTPB composite solid propellant are investigated. The defination of damage variable with the deinite physical meaning is put forward and the mathematical model of damage describing the damage propagation in composite solid propellant was developed. |
