Moreover, when outsider diameter D or minimum diameter at the root of notch d vary with root radius R at notch keeping constant, two different notch contours obtained have very little influence on the fracture strength of the material.

当缺口根部半径一定，仅改变外径D或缺口处最小直径d所得两种缺口状态对缺口强度的影响不大。

The computed 2 δ c values corresponded to the experimental deep notch root radius ρ 0. The relationship between fracture toughness and notch toughness depended on the relative size of effective deformed zone 2 δ c and mean free distance d B between bainites.

计算的2δc与测定的深缺口临界根部半径ρ0有对应关系。裂纹韧度与缺口韧度的关系取决于2δc与贝氏体之间的平均自由距离dB。
