摘要
评述了两种估算方法的估算步骤和特点,对两种方法在疲劳估算寿命的可靠性上做了一个简单的比较,对比结果表明:局部应力应变法比名义应力法有较高的精度和可靠度,通过实例验证了结论的正确性。
The estimation procedure and characteristic of these two methods have been evaluated, and we simply compared and analyzed the reliability of these two methods on estimating structure fatigue life. The conclusion showed that local strew-strain method is more accurate and reliable than nominal stress method and we used the example to prove the correctness of the conclusion.
