TL;DR: In this paper, a review of modeling and simulation effort in metal additive manufacturing taking place at U.S. Department of Energy national laboratories is presented, focusing on simulation and modeling.
Journal ArticleDOI
Implementation of a thermomechanical model for the simulation of selective laser melting
TL;DR: The present work describes continuum modeling of SLM as envisioned for eventual support of part-scale modeling of this fabrication process to determine end-state information such as residual stresses and distortion.
Journal ArticleDOI
Overview of modelling and simulation of metal powder bed fusion process at Lawrence Livermore National Laboratory
Wayne E. King,Andy Anderson,Robert M. Ferencz,N.E. Hodge,Chandrika Kamath,Saad A. Khairallah +5 more
TL;DR: In this article, a multiscale modeling strategy is described that will serve as the foundation upon which process control and part qualification can be built, including a model at the scale of the powder that simulates single track/single multilayer builds and provides powder bed and melt pool thermal data.
Journal ArticleDOI
Large-scale vectorized implicit calculations in solid mechanics on a Cray X-MP/48 utilizing EBE preconditioned conjugate gradients
TL;DR: In this article, a vectorized implementation of the EBE preconditioned conjugate gradients (PCG) algorithm is presented in the context of a nonlinear stress analysis code nike 3 d.
