Then, on the basis of the expression for notch strength of brittle material and the fundamental principle of probability theory, correlations between the statistical characteristic parameters o.
In order to predict effects on machined surface by developed notch-crack, crack extension mechanism of notch-crack-tip was investigated in cutting brittle materials.
为预测缺口裂纹对加工表面形成的影响，研究了切削脆硬材料时缺口裂纹的扩展。
