アルミニウムワイヤのネック部破断を対象としたS-N 曲線予測法

抄録

This paper addresses how to predict the S-N curves for the fatigue fracture of neck area in aluminum wires. Because the conventional prediction methods for S-N curve were based on the assumption of the thick bulk samples, the applicability of the methods to the thin aluminum wires was examined by comparing the predicted S-N curve with fatigue test results. The results indicated that the conventional prediction methods for S-N curve were applicable to the fatigue fracture of neck area in the aluminum wires. Especially, Manson’s universal slope method predicted the S-N curve with good accuracy.
