Relation between the Betti Number of Fatigue Fracture Surfaces and Stress Intensity Factors of Low Carbon Steel (JIS, S45C)

Relation between the Betti Number of Fatigue Fracture Surfaces and Stress Intensity Factors of Low Carbon Steel (JIS, S45C)

The study of fracture surfaces of materials is very important to understand failures in engineering elements, especially in structural products. However, it is not easy to evaluate fatigue fracture surfaces by using ordinary image analysis techniques. In this paper, we propose a new analyzing method...

Zusammenfassung:The study of fracture surfaces of materials is very important to understand failures in engineering elements, especially in structural products. However, it is not easy to evaluate fatigue fracture surfaces by using ordinary image analysis techniques. In this paper, we propose a new analyzing method to evaluate fatigue fracture surfaces from a view point of Homology.
