An approach is presented to predict fatigue life and energy dissipation based on the measurement of the electrical power consumption of an external heat source. In this method, the steady-state temperature profile of a specimen experiencing cyclic fatigue test is reproduced simply by externally heating the specimen with an electric coil with a DC source. The results show a direct relationship between the electric power consumption of heating coils and the fatigue plastic energy dissipation. This relationship is used as a tool to predict fatigue life.

基于外加热的疲劳寿命预测方法

提出了一种基于外部热源电能消耗测量来预测疲劳寿命和能量耗散的方法。在这种方法中，经历循环疲劳试验的样品的稳态温度曲线可以简单地通过使用直流电源的电线圈从外部加热样品来重现。结果表明加热线圈的电功率消耗与疲劳塑性能量耗散之间存在直接关系。这种关系被用作预测疲劳寿命的工具。
