It provides a summary of the complex interactions between material microstructure and cracks, classifying them with respect to the overall damage process with a focus on microstructurally short cracks and dynamic embrittlement. It furthermore introduces new concepts for the numerical treatment of fatigue microcrack propagation and their implementation in fatigue-life prediction models.This comprehensive overview of tMetalsFatigueAlloysFatigueMetalsFatigue.AlloysFatigue.620.1617620.166Krupp UlrichPh.
