- OS0315 Investigation of Appropriate Measurement Conditions for Fatigue Limit Estimation Based on Dissipated Energy for 304 Stainless Steel
抄録
In recent years, fatigue limit estimation method based on energy dissipation measured by infrared thermography is getting an increasing attention. In this method, temperature change due to irreversible energy dissipation during one loading cycle is measured for different levels of applied stress amplitude. Obtained relationship between temperature change and stress amplitude shows a significant inflection at certain stress level where temperature change due to energy dissipation shows steep increase. It is known that this stress level coincides with fatigue limit. In this study, measurement conditions for appropriate fatigue limit determination based on the energy dissipation are discussed in conjunction with (i) required number of loading cycles in each stress level, (ii) representative value in measurement area, and (iii) influence of loading history and fatigue damage accumulation.
