Varieties of dynamic intensity factors in the crack - tip field , extensions of cracks going through the joint planes for different distances between hole and joint were analyzed especially under the condition that the initial cracks and joint planes had different separation angles 实验结果分析表明,爆生裂纹穿过节理面时,裂纹尖端的动态强度因子和裂纹扩展速度显著下降,穿过节理面后,强度因子又增强;裂纹穿过节理面时,裂纹会沿节理面偏离一段距离后沿原方向继续扩展。
