Influence of Microstructure and Surface Roughness on Fatigue Initiation in Extruded Aluminum
Comprehensive experimental data on the fatigue properties of extruded Al6082-T6 is used together with crystal plasticity simulations to investigate the microstructure and surface roughness influence on fatigue initiation. Thesurface roughness of the specimens used in the experiments was mapped with White Light Interferometry (WLI) and the location of the fatigue initiation sites was identified and
