Correlation between the strain range and fatigue crack growth rate was investigated using Type 316 stainless steel. Crack growth rates were obtained by pull-push axial fatigue tests using cylindrical specimens. The obtained crack growth rates correlated well with the strain intensity factor, in which γ^<-0.5> singularity was assumed at the crack tip. The integration of the regression curve of the obtained crack growth rates agreed well with fatigue lives obtained using conventional fatigue tests.
