The through-thickness texture of an industrial hot-rolled Al-Mg-Si alloy plate is investigated both experimentally and numerically. The texture has been determined continuously from the plate center to the surface with large-scale electron backscatter diffraction scans. In accordance with literature results, a stable cube component and a strong brass component were found in the center, while the rotated cube component dominates the texture outside of the center region. A viscoplastic self-consistent polycrystal model including non-octahedral slip and grain shape evolution is shown to provide very good numerical predictions of the hot rolling texture. It captures the stability of the cube component and the gradients of the shear and brass component. However, it overestimates the intensity of the rotated cube component and wrongly predicts a stable goss component across the plate thickness. The calculation of deformation histories, which serve as boundary conditions for the polycrystal model, is presented and discussed.
