将“人工楔块”上裂技术用于表面裂纹疲劳止裂在对表面裂纹试件进行了低频拉伸和高频弯曲两种载荷下的有楔、无楔试验后,发现“人工楔块”上裂技术对于表面裂纹同样有显著的止裂效果

Fatigue experiments of surface crack with wedge and without wedge subjected to low freqency tension and high frequency bending have been performed. The results show that crack arresting technology of "artificial wedge" has remakable effect on suface crack
