Results of a Monte Carlo simulation of the initiation stage of fatigue failure of aluminum alloys are described. Initiation processes simulated are: (1) nucleation ofcracks at particles at or near the alloy surface; (2) early growth of microcracks with lengths on the order of the grain size; and (3)
Prior to the crack initiation, damage is most often localized at a scale below the size of the classical representative volume element of the continuum mechanics. This allows the stress and strain analyses in a component to neglect the strain-damage coupling at macro-scale. At the micro-scale, this
