513 応力集中部のCritical Distanceによる疲労寿命評価法の妥当性検証(締結・接合部の力学・プロセスと信頼性評価(3),ものづくりにおける基礎研究と先端技術の融合)

I perform the fatigue life evaluation of the stress concentration to own the stress singular place by Manson - Coffin low with a plasticity strain range, but, as for the evaluation, it is difficult. Therefore I introduce it because I inspected the validity from the breakdown test result of the torque limiter whether I can evaluate it by binding fatigue and Critical Distance at the time of the destruction and relations of the stress value at that time together by a straight line as one approach for a high cycle.
