root of notch

The stress triaxiality and equivalent plastic strain distributions at the minimum cross-section of specimens with different notch root radius are similar for such three kinds of materials.

三种材料不同缺口根半径试样最小横截面上应力三维度和等效塑性应变分布形态相似。

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 influences of the root curvity radius, length, end ellipticity of a notch and the forms, materials of the sample on the failure assessment diagram were totally studied.

较全面地研究了缺口根部曲率半径、缺口长度、缺口端部椭圆率以及试样类型、材料等对失效评定图的影响。

The actual control condition at the root of the notch is more problematic.

在缺口根部的实际控制条件是更难捉摸的.

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。
