Introducing an Enhanced Friction Model for Developing Inertia Welding Simulation: A Computational Solid Mechanics Approach

Friction welding is a solid-state process that generates heat through mechanical friction between workpieces in relative motion to one another, with the addition of lateral force called upset plastically displace and fuse materials. One key problems during modeling processes implementation model. Coulomb model was proposed by researchers for computational solid mechanics (CSMs) process, however this law based on sliding motion. Norton also others, while simplifications limitations are caused coincidence reality. In paper, modified be employed inertia welding. A continuous remeshing technique used avoid mesh distortion problem. Consequently, successful prediction temperature distribution, thermal history, equivalent plastic deformation, axial shortening stress distribution made. The comparisons results study literature showed implementing methodology leads achieving high accuracy results.
