Abstract Scope |
Modeling and numerical simulation provides a comparatively low-cost method in understanding the complex interactions in the powder based directed energy deposition (DED) process. Physical phenomena occurring at different length scales – such as grain growth at the micro-scale, temperature changes and evolution of melt pool geometry at the meso-scale, and temperature distribution and changes in residual stress at the macro-scale are challenging to solve through a single model. Studies have employed both separate models as well as coupled techniques to explain these phenomena in DED in greater depth. Once a numerical model is established and validated, it can be further used to optimize parameters for specific purpose, saving both time and costs for experiments while providing insight into how changes in parameters affect the printed part. This paper aims to review the current status of the modeling techniques and numerical simulations utilized for the DED process. |
