| Abstract Scope |
Shear Assisted Processing and Extrusion (ShAPE) is an emerging high-strain, solid-phase processing technique. It turns the metal powder, flake, or billet into high-performance parts without melting the feedstock materials. Currently, most of the studies on ShAPE are based on experiments, which can be costly and limited in data acquirement. To better understand the processing parameters on the performance of the processed parts, a computational model is required. In this study, we develop a smoothed particle hydrodynamics (SPH) model to simulate the ShAPE process. Due to its meshfree and Lagrangian nature, SPH can handle large plastic deformation without heavy re-meshing and track the history-dependent variables more easily. Model predictions evaluate the effects of the die geometry, rotation speed, billet advancing rate, and thermal boundaries on the material flow, stress-strain state, and temperature of the extruded parts. We show that predicted strains and temperature are in good agreement with the experimental data. |
