| Abstract: | Aiming at the problems concerning the composite solid propellant with large deformation in the matrix and interface debonding around the filled particles,an improved Mori-Tanaka method was developed.At the same time,in order to verify its effectiveness,a simulation method for the interface debonding of the composite solid propellant consists of random filled particles was also put forward.Finally,a computational case of one kind of composite solid propellant was investigated.It is demonstrated that the resu... |
