| Abstract Scope |
In this work, we developed a meshless approach that utilizes a combination of Smoothed Particle Hydrodynamics (SPH) and FEM to obtain a physics-based model capable of capturing the thermo-mechanical behavior of Linear Friction Welding (LFW) process in 3D. The meshless framework is implemented using a commercial FEA package using custom defined application programming interface (API). Subsequently, we employed the developed model to simulate and investigate flash formation and burn-off distance of LFW of Ti-6Al-4V parts. The simulated upset agreed well with FE simulation and experimental data, while the simulation’s weld time of 0.6-0.75 seconds did not match with the experimental trial. This work addresses the gap in modeling LFW using commercial software tools, which are limited to 2D due to large deformation. This work was funded by the U.S. Air Force, Phase II SBIR Contract FA8650-19-C-5050, awarded to ACT, Inc. |
