| 摘要 |
本文通过霍普金森杆冲击试验，分析了不同角度下试件的破坏过程的不同，试样表面的裂纹由出现到发展为贯通裂纹、直至试样失效破坏的各个阶段中，预制裂纹的角度的变化对试件裂纹产生直至试件破坏的时间影响较小，但预制裂纹的角度对裂纹的扩展方式以及扩展方向有较大的影响。

| Abstract |
Through hopkinson bar impact test, this paper analyzes the different failure processes of specimens at different angles. In each stage from the appearance to the development of the crack on the specimen surface to the failure and failure of the specimen, the change of the Angle of the prefabricated crack has little influence on the time of the crack generation to the failure of the specimen. However, the Angle of the prefabricated crack has great influence on the propagation mode and direction of the crack.
