摘要
通过对半无限板边裂纹的零维对流燃烧和变形扩展的模拟分析，揭示了固体推进剂裂纹燃烧扩展耦合的基本模式：燃烧流场和裂纹变形扩展相互作用，推进剂塑性变形对燃烧性能的影响，为燃烧断裂的深入研究提示了方向。
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
