A database on the fatigue strength of metallic materials was compiled by collecting the experimental fatigue data of the last 20 years in Japan on a nationwide scale as a joint project of JSMS Committees on Fatigue and on Reliability Engineering. By sorting the fatigue data on carbon steels for machine structural use, the authors classified them into several populations and analyzed P-S-N characteristics based on the stress dependence of the fatigue life distribution. The analytical results were in good agreement with the statistical aspects of the practical fatigue data.
