About us
Research projects on fatigue are being conducted by using:
・ Fatigue testing technologies in low-, high- and giga-cycle regions.
・ Measurements of fatigue crack growth rates (not only for large cracks but also for small cracks).
Examples of Research Projects
・Evaluation of gigacycle fatigue properties on metallic materials by using ultrasonic fatigue testing.
・Predictions for gigacycle fatigue strength of high-strength steel.
・Development of in-situ small fatigue crack observation system and elucidation of small crack growth mechanisms.
