| Abstract Scope |
In this study, simulations of varying tool geometries were conducted through smoothed particle hydrodynamics (SPH) simulations of additive friction stir depositions (AFSD) in-order to elucidate deposition mechanics for AA6061. The simulations compared influence of tool face diameter changes, and the resulting thermo-mechanical behavior with a focus on material flow behavior and heat generation resulting from frictional forces and plastic deformation. The simulation results revealed a relative difference in resulting heat generation beneath the tool face from diameter changes. Additionally, results from the SPH simulations showed that changes in tool geometry and resulting heat generation produce different flash generation and deposition behaviors. The rotational, radial, and traverse flow interactions visualized by AFSD simulations explained the resulting changes in thermal heat generation and subsequent material flow changes during material deposition. The resulting simulations show how the meshless computational tools are able to elucidate material behavior in this solid-state thermomechanical AM process. |
