This manual explains the principle, life prediction, data acquisition, processing and expression of the strain energy time-dependent fatigue crack initiation life prediction method (hereinafter referred to as the strain energy method). This specification is suitable for predicting the time-dependent fatigue crack initiation life of high-temperature metal structural materials. It can be used for material research and improvement, quality control and failure analysis, and provides the mechanical behavior of materials for component life prediction systems.
