| Abstract Scope |
Metal additive manufacturing processes are characterized by extreme discrepancies in length and time scale between the critical physical phenomena and that of components. As a result, models for AM are consistently challenged to balance approximations to process physics and practical utility for answering engineering questions. This presentation will describe a suite of AM process and microstructure models developed at Oak Ridge National Laboratory designed to aid in evaluating component quality. The models include melt pool thermal simulations at multiple fidelities, defect predictions, cellular automata grain structure simulations, thermomechanics, and coupling to mechanical property predictions. Specifically, the key tradeoffs in speed and fidelity will be discussed, especially in the context of computing resources ranging from workstations to leadership class supercomputers. Additionally, coupling to physical process data and opportunities for real-time digital twins will be described. |
