Abstract

Abstract

Fatigue crack of materials induces very large calamity because of its abruptness. According to literature researches, fatigue destroy hold 80~90% in all of mechanical invalidation. In this paper, we adopt three kinds of φ 9.50.57mm thin-wall tube samples, and finish low cycle fatigue test at 5 kinds of strain levels. We get the relationships of Δε_t-N and fatigue imitation function. Furthermore, the fatigue crack microstructure is analyzed and the mechanism of fatigue is discussed.
