Abstract

Highlights: Review of dislocation dynamics simulations & micro-scale experiments of metal fatigue. Fatigue dislocation structure evolution, size effects and crack. Current limitations and future outlook regarding the modeling and experiments are discussed. Abstract: This review paper providing a comprehensive review of insights gained from cyclic loading discrete dislocation dynamics simulations and micro-scale fatigue experiments on dislocation structure evolution, size effects on fatigue life and fatigue strength, and crack initiation/propagation in metals.
