| Abstract Scope |
A direct energy deposition approach to modeling of additive manufacturing using ANSYS Additive is adapted to the modeling of Additive Friction Stir Deposition (AFSD) of AA 7075-T6 material. Experimental data is collected by inserting thermocouples into the part during deposition to gather temperature histories at various locations. These data were then compared to the simulation model for validation, where reasonable agreement was seen with the experiment, after a period of model adjustment, where appropriate boundary conditions were refined in order to better match those that occurred during the physical build. The current effort aims to enable manufacturers to predict thermal histories, final part shape, and residual stresses in AFSD-fabricated parts. If successful, this advancement will help to speed the development of AFSD as a manufacturing process, potentially leading to broader industrial adoption and innovation. |
