Abstract
Nowadays, additive manufacturing (AM) becomes an attractive technique for constructing complex-shaped metal parts for a large number of industrial fields. However, the wide application of metal AM is still rather poor due to the number of unsolved scientific and industrial problems. For instance, the presence of the anisotropic microstructure and texture specific for additive materials essentially complicates a full understanding of the material deformation behavior. Thus, the present work aims to numerically investigate the inhomogeneity of the mechanical response of an AlSi10Mg alloy produced by selective laser melting at the grain scale. The stress and plastic strain fields are analyzed under uniaxial tension along two perpendicular directions. The deformation-induced surface roughness patterns are demonstrated as an additional source of information for a deeper understanding of an additive material deformation behavior.
