摘要：

A technique for fatigue life prediction of metals is presented based on a microstructure-sensitive estimation of plastic strain energy per cycle. The approach enables rapid prediction of temperature evolution, estimation of cyclic plastic energy, and fracture fatigue entropy. Theoretical and experimental results are presented for low-carbon steel 1018 and aluminum 7075-T6 specimens. It is shown that the approach realistically predicts the fatigue life of metallic specimens.
