| Abstract Scope |
This present study employs smoothed particle hydrodynamics (SPH) to simulate the process of additive friction stir deposition (AFSD) and study the evolution of microstructure using crystal plasticity. The numerical analysis studies the effects of various process parameters such as tool speed, material feed-rate and, cooling effects to characterize the AFSD process. The large deformations involved in this process makes it challenging to predict the material motion through
traditional grid-based methods. The reduced computational time is one such benefit that is offered in this approach over other methods such as Coupled Lagrangian-Eulerian (CEL). The stress, strain fields and the temperature history during the process are considered and the microstructure evolution is studied in detail by tracking the deformation of material points in crystal plasticity. The results are compared with experiments to validate the method. |
