采用SHTB技术对纤维增强复合材料裂纹动态起裂行为进行了实验研究。使用应变片方法确定了裂纹的起裂时间，结合有限元数值模拟得到了裂纹的起裂韧性；同时观察了裂纹在冲击载荷作用下的裂纹起裂和扩展方式，分析了纤维的铺层角度对裂纹起裂和扩增的影响。 |

It is investigated that the initiation of crack in fiber-reinforced composites under impact loading by SHTB experimental technology in this paper. The initiation time of crack is measured by strain gauge on the sample. The fracture toughness of the composite material is determined by FEM numerical simulation. The patterns of fracture of the crack under impact are observed and the influence of plies angle on the growth of the crack is analyzed. |
