Abstract
Evaluation of fatigue limit of every component is an important issue to ensure the safety of engineering products. However, determination of fatigue limit by traditional WOhler method is a time consuming task and costs too much. Recently a technique besed on the measurement of dissipated energy using infrared thennography is paid attention for rapid and convenient evaluation of fatigue limit. However, there have been few reports considering application of the technique to stress concentration parts. In this study, the technique is applied to a notched specimen made of stainless steel in order to verify its applicability to real engineering products.
