    Initial contribution When metal breaks after being bent or loaded over and over, even if the load is small.

    The progressive and localized structural damage that occurs when a material is subjected to cyclic or fluctuating stresses, typically leading to the formation and propagation of cracks even when the peak stress remains below the ultimate te…

    This should state that fatigue failure occurs below the material's yield strength, and mention crack initiation, propagation, and final fracture as the three stages.

    Good plain-language start. Worth distinguishing high-cycle from low-cycle fatigue in a later revision.

    Accepted AI-assisted revision Fatigue is a progressive structural damage process that occurs when a material is subjected to cyclic loading. This phenomenon leads to failure at stress levels significantly lower than the material's ultimate tensile strength or yield stre…

    Make it precise: say failure happens under cyclic loading below the yield strength, and name the three stages (crack initiation, propagation, final fracture).
