Advanced Modeling and Simulation of Thermal Kinetics in Additive Manufacturing

Abstract

Major Goals: Additive manufacturing (AM) is inherently a thermal process where layered building is achieved through directed energy input with melting and solidification, energy input for sintering without melting, or binding through a separate agent (e.g., a chemical reaction). In all cases, heat input and its time-dependent propagation through the part plays a critical role. In this project, AM thermal kinetics are studied in two sub-projects. These are: 1) crystal growth modeling in a new powder bed silicon carbide AM process 2) residual stress modeling in wire-arc AM for magnesium alloys.
