摘要
应用应力场强法对旋弯疲劳和扭转疲劳极限进行了分析,并通过3种金属材料的旋转弯曲和扭转疲劳试验加以验证,结果表明,旋转弯曲疲劳极限和扭转疲劳极限之间的关系同解析表达式给出之间的吻合得非常好,因此得到结论,应力场强法能够比较好的描述两种疲劳强度极限之间的关系。
The rotary bending fatigue limit and torsion fatigue limit stress is analyzed using the stress field method. Also the identification has been gotten . The result of test indicates that it is coincidental well with the resolution express, the fatigue limit expresses gotten by the stress field method are practicable and reasonable.
