The effects of strain rate and strain wave shape on the fatigue life of SUS 316 and SCMV 3 (11/4Cr-1/2Mo)steels have been investigated using several types of strain wave shapes such as triangular, truncated and sawtooth wave shapes. The data have been analyzed by the strainrange partitioning method proposed by MANSON, HALFORD, and HIRSCHBERG. A new method has been proposed and used for partitioning the inelastic strain range in applying the strainrange partitioning method. Four component strain range versus life relationships have been obtained by both interaction damage rule and conventional damage rule.
