| 摘 要： | 对复合固体推进剂拉伸变形破坏过程进行了原位扫描电镜观察,采用数字图像相关方法分析了不同变形阶段电镜图片,得到了推进剂细观表面变形场,探讨其在拉伸过程中的细观破坏机理。研究结果表明,数字图像相关方法与扫描电镜相结合为复合固体推进剂在细观尺度下的测量与破坏机理分析提供了新的途径,也为推进剂细观数值模拟提供了实验依据。

| Abstract: | The tensile deformation and fracture behavior of composite solid propellant were observed by in-situ scanning electron microscopy. The obtained microscopy images under different phase were analyzed by Digital Image Correlation Method(DICM).The microscopic deformation field and failure characteristics of composite solid propellants were obtained. The results show that DICM coupling with SEM is a ideal approach to measure and study the failure of propellant on a grain scale and it can provide the experimental evidence for numerical simulation. |
