摘要
利用基于热力学的损伤理论,从理论上分析了损伤变量与疲劳寿命的关系,又通过基于电阻值的损伤测量实验,得到电阻测量值与损伤寿命的关系,从而为金属构件的剩余寿命找到了一个可靠的预测方法。
The relationship between damage variables and fatigue life is theorically analysed via damage theory based on thermodynamics.The relationship between risistance and damage life is obtained according to the experiments of risistance testing.A reliable method is given to forecast the residual life of the metal structure.
