摘要

•Simulations explain the influence of advancing direction on residual stresses.•Fatigue life in laser peened stainless steel 316L specimens can be increased (+471%) by optimizing the pulse sequence.•3D FEM model allows to simulate massive parallel LSP over real geometries.•Good match between simulations and experimental results.
