| 摘 要： | 从微观、细现和宏观角度分析了围压对NEPE推进剂强度的影响.在细观尺度范围内讨论了剪切阻力、张开性裂纹和空洞的影响,并给出了基于双剪强度准则的围压对推进剂强度影响的模型.三种尺度的结合还须更多的研究.

| Abstract: | The effects of confining pressure on the intensity of NEPE propellant from micro,meso and macro scale were discussed in this paper.The effects of shear resistance,and opened crack and hole were analyzed at meso-scale.The model based on double-shear intensity rule was given out.The integration of the three kinds of sizes was needed to be researched much more. |
