4) U-shaped notch
U形切槽
1.
However,a sharp crack can hardly be prepared for the specimen of quasi-brittle materials,alternatively it is reasonable to consider a U-shaped notch,then use stress concentration factor(SCF) to characterize the peak stress at the notch bottom.
三点弯曲梁被广泛应用于测试材料的断裂性能,但对准脆性材料难以制作尖锐的裂纹,因此考虑三点弯曲梁具有U形切槽,此时可以用应力集中系数来表征切槽端部的应力峰值。
