Principle of the ultrasonic fatigue testing
By using resonance, strong vibrations take place in specimens, which cause fatigue failure. This method is far different from conventional fatigue testing that uses physical force, meaning that expertise is necessary to use this method appropriately. We have used this method for over 20 years, accumulating the expertise and data.
Applications: Very high cycle or gigacycle fatigue tests on high-strength metallic materials
