  • RPI SCOREC - Technical Reports
    12 Pages 485 500 Editor J Fish Abstract A nonlocal multiscale model in time domain is developed for fatigue life predictions The method is based on the mathematical homogenization theory with almost periodic elds The almost periodicity relects the effects of irreversible deformations in time domain in the form of accumulation of damage Multiple temporal scales are introduced to decompose the original boundary value problem into micro chronolocical temporal unit
