Analysis of additively manufactured anisotropic microstructures through crystal plasticity frameworks

Abstract. In additive manufacturing processes, the resulting products might have highly anisotropic granular morphologies due to complex thermal history. The most commonly observed morphology is columnar structure. of grains accompanied by orientation alignment leading plastic anisotropy. It has been shown in a recent study through local crystal plasticity calculations that evolution does not influence mechanical behavior without considering texture [1]. However, frameworks do consider effect grain size which could be complicated high aspect ratio grains. This aims investigate developed structure on macroscopic response both and non-local address capacity these models capturing realistic response. An additional subroutine implemented (see [2]) into obtain slip resistance values at each material point based geometries misorientations. allows dependent yielding crystals.
