| Abstract: | Zero dimensional convective combustion,and crack deformation and propagation of solid propellants were simulated for the edge cracked semi infinite plane.The results reveal the basic patterns of the coupling i e the interaction between the convective combustion flow field and crack deformation and propagation,and the effect of the visco plastic deformation on the combustion characteristics of solid propellant.So it makes it clear that what to do in the future about the theme of crack combustion and propagation |
