The Additive Friction Stir Deposition (AFSD) process is a novel low-temperature solid state additive manufacturing approach that allows for fast and scalable manufacturing of metal alloys. It consists of a hollow tool through which the feed material is delivered. The rapid rotation of the tool generates heat through friction at both the tool-material and material-substrate interface. The feed material, heated and softened, is fed through the tool and bonds with the substrate at the interface. The tool also has a transverse motion which results in the deposition of a single track of material. Subsequent layer deposition make 3D parts. Due to the presence of complex heat generation and transfers, large plastic deformation and bonding, AFSD is a thermo-mechanical process whose physics are complicated to fully understand experimentally. Hence numerical simulations are essentials to help understand this technology better.
The aim of this project is to develop and validate a new numerical approach to accurately model AFSD. This approach will be based on the Material Point Method, a meshless method that can easily handle arbitrary large deformation, and be used to understand the evolution of temperature and strain during the deposition. Validation of the model will be done using state-of-the-art characterization of metal flow paths using new strain mapping techniques and X-ray tomography. This project will allow the development of a wide range of skills from materials science, metallic alloys, applied mathematics, computer science, and engineering.
