Hybrid SPH-FEM solver for metal cutting simulations on the GPU including thermal contact modeling

This paper presents a hybrid Smoothed Particle Hydrodynamics (SPH) – Finite Element Method (FEM) solver for metal cutting simulations on Graphics Processing Units (GPU). For the first time in chip formation simulation, heat transfer between an SPH model of workpiece, and transient FEM temperature tool, is established. validation, performance modeled thermal contact two numerical domains compared with commercial software. The sensitivity implemented SPH-FEM parameters investigated further insights into modeling are generated. Overall, newly developed saves computational tool side pure method enables more efficient high-fidelity simulations. By clearly defining at tool-chip interface, simulated surface agrees well experimental measurements literature.
