本文论述了多轴载荷下的无限寿命疲劳设计方法。提供了对称循环和非对称循环下的弯扭复合疲劳设计公式和三轴应力疲劳设计公式。并给出了弯扭复合应力下的疲劳试验数据和疲劳设计数据
This article discusses the infinite life fatigue design method under multi-axial load. It provides the composite design formulas of flexural and torsional fatigue and asymmetric cyclic fatigue under symmetrical and triaxial stress. The fatigue test data and fatigue design data under combined bending and torsional stress are given
