The ultrasonic fatigue test is a method used to study the fatigue behavior and properties of materials under high-frequency cyclic loading. Typically, ultrasonic vibrations are applied to the samples under high-frequency cyclic loading (20-100kHz). This high frequency loading results in a rapid accumulation of fatigue cycles, allowing fatigue life assessments to be conducted in hours or days instead of the weeks or months that conventional tests might require. However, there are some challenges associated with ultrasonic fatigue testing, such as difficulties in accurately measuring stresses and strains at high frequencies, the need for specialized equipment and potential for unreliable results due to the unique loading conditions. In this study, in order to solve the problem of ultrasonic fatigue test, conventional fatigue test and ultrasonic fatigue test were performed based on SS400 material. The results were compared and leading to a plan for enhancing the reliability of ultrasonic fatigue data.
