10.In this paper,the relation between the fatigue limits of plain-and notched-specimens and fatigue thresholds together with the mechanism of FCP behaviors in short cracks was evaluated. The crack propagation behaviors in short cracks can be generally expressed as,where f(a)is a function of the crack length and specimen geometry.
本文对于板状及缺口试样的疲劳极限和门坎值的相互关系以及短裂纹的疲劳裂纹扩展机制也一起进行了评述,短裂纹的裂纹扩展行为可以一般地表达为: ΔK_(th)=f(α)Δσ_(th)(πα)~1/2式中,f(α)为裂纹长度与试样几何形状的函数。收藏指正
