摘要: 对垂直、剪切以及斜向等各种冲击载荷作用下裂纹的动态响应进行了数值模拟，得到了一系列随时间变化的动态应力场以及应变场图；根据其定义，计算出了相应的动态应力强度因子，进而分析了斜向载荷作用下裂纹起裂情况，并对最优断裂问题进行了阐述。

Abstract: The numerical simulation was carried out for the dynamic response of crack subjected to the normal, shear and oblique impact loads. The dynamic stress field and the strain field were obtained. According to its definition, the corresponding dynamic stress intensity factor (DSIF) was calculated. The situation of initiation of crack impacted by oblique loads was analyzed, and the optimization fracture by stress pulses was discussed.
