摘要:计算了单边椭圆缺口试件(SENCP)高应变区裂纹的J积分失效评定曲线(FAC),考察了影响FAC的几种因素。结果表明:在外加载荷与塑性屈服载荷之比(Lr)1.0时,用R6通用失效评定曲线进行结构高应变区裂纹断裂评定与疲劳剩余寿命估算是安全的。
The J-integral failure assessment curves(FAC)of cracks at the semi-elliptical single edge notch crack plates(SENCP)are caculated,some factors affecting FAC are dis cussed in details. It is safe to use R6 general FAC for the fracture assessment and fatigue life evaluation of high strain zone flaws in the case of L_r≤1.0.
