Timetable: 10:00 - 11:00 a.m. CET time
Speaker: Michele Merelli
Language: English

Explore cutting-edge simulation methodology for Friction Stir Welding (FSW) and Friction Stir Spot Welding (FSSW), developed through collaboration. This innovative approach treats metal bodies as non-Newtonian fluids, enabling accurate prediction of joining strength and material behavior under various operational parameters. Verified against both experimental results and reference studies, this methodology provides a comprehensive solution for welding process optimization. This presentation showcases a powerful methodology that enables precise prediction of joining strength and material behavior, specifically validated for aluminum series materials.

• Non-Newtonian fluid modeling approach for metal behavior
• Temperature and shear rate-dependent viscosity analysis
• Comprehensive parameter optimization including rotational and insert speeds, feed rate variations, tool geometry effects,joining diameter optimization and material mixing uniformity prediction.

In conclusion, we will cover verified simulation results for both FSW and FSSW processes for 5000-series and 6000-series aluminum interactions.
