    Deep Rolling for Tailoring Residual Stresses of AA2024 Sheet Metals

    Deep Rolling as a well-known mechanical surface treatment process is investigated with the objective to tailor residual stress profiles over the sheet metal thickness. Experiments are performed in a milling po...

    On the Effect of Testing Frequency on High and Very High Cycle Fatigue Behavior of AA2024-T3, Ti-6Al-4V, and Inconel 718

    An increase of testing frequency to reduce the testing time could affect the fatigue behavior of metallic materials. The current paper investigates the effect of testing frequency on the high and very high cyc...

    Phase-field modelling for fatigue crack growth under laser shock peening-induced residual stresses

    For the fatigue life of thin-walled components, not only fatigue crack initiation, but also crack growth is decisive. The phase-field method for fracture is a powerful tool to simulate arbitrary crack phenomen...

    Fatigue Crack Propagation Influenced by Laser Shock Peening Introduced Residual Stress Fields in Aluminium Specimens

    Laser Shock Peening (LSP) enables the generation and modification of residual stresses deep below the surface of metallic components. LSP-induced residual stress profiles provide penetration depths of compress...
