An online approach is proposed to predict the fatigue life of metallic specimens under cyclic loading using the concept of thermoelectricity. The working principle of the methodology is described, and experimental results are performed with a fully reversed bending fatigue testing apparatus to evaluate the efficacy of the approach. Results are presented that correlate the measured thermoelastic potential for low‐carbon steel 1018 specimens measured via an infrared camera. It is shown that the application of thermoelectricity provides a practical methodology for early prediction of fatigue.

热电在金属疲劳中的应用

提出了一种在线方法，利用热电概念来预测金属试样在循环载荷下的疲劳寿命。描述了该方法的工作原理，并使用完全反向的弯曲疲劳测试设备执行了实验结果，以评估该方法的有效性。给出的结果与通过红外热像仪测量的低碳钢1018样品的热弹性势相关。结果表明，热电的应用为疲劳的早期预测提供了一种实用的方法。
