Abstract

When the compression coil springs are subjected to high cyclic stress, fatigue crack sometimes initiates and propagates from small scratch or defect produced in the manufacturing process. However, there are a limited number of studies on the fatigue behavior of high-strength spring steel in the presence of small scratch. In this study, the fatigue tests were conducted to examine the uniaxial fatigue behavior of a high-strength spring steel (JIS G 3561, SWOSC-V) in the presence of small circumferential notches. Based on \(\sqrt{area}\) parameter model, the sensitivity of hard steels, including a high-strength spring steel, to small scratches was qualitatively and quantitatively examined.
