Abstract Scope A Monte Carlo (MC) based method has been developed to simulate 3D microstructural evolution during metal additive manufacturing. Resulting microstructures are now being used in direct numerical simulation (DNS) of material performance to establish a workflow for full process-structure-property relationships within simulations. Here, a synthetic MC-produced “additively manufactured” tube is considered and its elastic response under simple loading conditions is considered. Process simulations were performed at a variety of processing conditions, yielding columnar, equiaxed and columnar/equiaxed grains. DNS results demonstrate that, even within the elastic regime, grain morphologies resulting from processing differences, can have significant impact on departures from a homogenized strain response often approximated in many approaches. Sandia National Laboratories is a multi-mission laboratory managed and operated by National Technology and Engineering Solutions of Sandia, LLC., a wholly owned subsidiary of Honeywell International, Inc., for the U.S. Department of Energy’s National Nuclear Security Administration under contract DE-NA0003525.
