Actual structures are exposed to arbitrary average stress, and evaluation using a modified Goodman diagram is widely performed. However, it has been reported that there is a material to which these diagrams cannot be applied, and in some cases the fatigue limit drops significantly. Therefore, the authors developed a method to quickly estimate fatigue limit using temperature change and plastic strain energy measured by IR thermography, and examined its effectiveness.
