Product Overview:

Friction Stir Welding (FSW) is a solid-state joining technique that utilizes frictional heat and plastic deformation generated by a rotating, non-consumable welding tool. This tool interacts with the contact surfaces of the materials being joined. While experimental studies on FSW can be time-consuming and expensive, numerical analysis has become increasingly popular in recent years to address these challenges. Various simplified numerical models have been developed to explore the complex thermo-mechanical phenomena involved in FSW.

This simulation video focuses on a thermo-mechanical finite element model based on the Coupled Eulerian-Lagrangian (CEL) method to simulate the FSW process for AA 6082-T6 alloy. Abaqus/CAE software is used to replicate the welding phase of Friction Stir Welding. The video demonstrates the steps of the numerical simulation, highlighting how the boundary conditions and tool geometry are evaluated using the CEL method. During the process, the tool’s rotation generates substantial heat, raising the temperature of the aluminum alloy. The simulation consists of three steps and employs a dynamic explicit temperature method.

Key Topics:

• Modeling aluminum plates using the Eulerian-Lagrangian method.
• Exploring the use of user-defined subroutines for custom modeling needs.
• Visualizing temperature profiles and material behaviors during the welding process.
