However, the wid application of metal AM is still rather poor du to the number f unsolved scientific and industrial problems. For instance, the presence of the anisotropic microstructure and textur specific for additive aterials ess ntially complicates a full understanding of th material deformation behavior. Thus, the present work aims to numerically investigate the inhomogeneity of th mechanical r spo s of an AlSi10Mg lloy produced by selective laser melting at the grain scale. The stress and plastic strain fields ar analyzed under uniaxial tensi n along two perpendicular dir ctions. The deformation in uced surface roughness patt rns are demonstrated as an additional source of information for a deeper understanding of an additive material deformation behavior. © 2021 The Authors.
