Abstract Scope |
In this study, particle tracking in smoothed particle hydrodynamics (SPH) simulations of additive friction stir depositions (AFS-D) were conducted in-order to elucidate deposition mechanics. The SPH model was validated using experimental depositions of two feedstock varieties, including anodized AA6061-T6 feedstock and AA6061-T6 copper wire core feedstock, to represent flow behavior from different regions of the feedstock. The experimental results revealed that the anodized oxides on the outside of the feedstock flowed to the retreating side, whereas the copper wire in the center of the feedstock migrated to the advancing side. Particle tracking results from the SPH simulations showed that, in general, particle movement is limited to directly beneath the feedstock. The rotational, radial, and traverse flow interactions visualized by AFS-D simulations explained the advancing and retreating side biases experienced by the internal copper wire and surface oxides on the anodized feedstock. |
