Abstract

According to linear fracture mechanics the crack growth rate is controlled by the stress intensity factor, so the non-singular stress has no effect on the growth rate. While several experimental data by Kitagawa et al. [1] and Liu et al. [2] more or less support this principle, some data indicate that the non-singular stress does influence the crack growth rate. Authors [3, 4, 5] already investigated the fatigue crack progress behavior of the magnesium alloy under biaxial stress. As a result, it was suggested that existence of a stress parallel to a crack affects crack progress velocity in AZ31B. In this research, fatigue crack propagation tests of Titanium were conducted under conditions of biaxial loading in order to investigate the effect of non-singular stress cycling. It is because the crystal structure of titanium is the same as magnesium. As a result, we clarified effects of biaxial stress condition for fatigue properties of Titanium.
