Fatigue Property Group

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).

Specialized Research Field

(Examples of Research Projects )

  • Evaluation of gigacycle fatigue properties on metallic materials by using ultrasonic fatigue testing.
  • Analysis of small internal cracks and 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.
