Abstract Scope Linear friction welding (LFW) is a solid-state joining process in which a weld between two metals is formed by combined action of frictional heating and forming force that creates a weld interface. Due to large deformation phenomena, commercially available software tools are limited to modeling of LFW in 2D using Finite Element Method (FEM) with adaptive mesh controls. 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 LFW process in 3D. The developed model is employed to simulate and investigate flash formation and burn-off distance in surrogate welds. The simulation results agreed well with FE simulation and experimental data. This work was funded by an U.S. Air Force Phase II SBIR program, Contract FA8650-19-C-5050, awarded to ACT Inc.
