切口系数 meaning in Chinese

notch coefficient
notch factor

Energy estimating approach of fatigue crack initiation life for welded steel structures is obtained by using molski - glinka energy density equation , introducing the worst - case fatigue notch factor , and considering the effects of residual stress on fatigue
本文采用应力应变能密度的molski - glinka方程，建立了一种预测焊接钢结构疲劳裂纹形成寿命的能量方法。该方法引入了极值疲劳切口系数，并考虑了焊接残余应力对裂纹形成寿命的影响。
