Abstract Scope |
There is significant interest in high-fidelity process modeling for additive manufacturing (AM) techniques. Modeling and simulation can provide the insight for a rational design by addressing the basic science and engineering needs for AM process, leading to a mechanistic understanding of processing-structure-property relationships, which are fundamental to design and develop innovative fabrication techniques. At mesoscale, a high-fidelity numerical model including heat transfer, fluid flow and mass transport, is developed in MALAMUTE (MOOSE Application Library for Advanced Manufacturing UTilitiEs) to simulate the melt pool physics. Ray-tracing capability in MOOSE is leveraged to accurately tract the interaction between powder addition and laser heat source. The temperature, chemical composition and solidification rate of melt pool can be predicted and thereafter used in lower-length scale model to simulate microstructure evolution. |
