This example problem shows how to simulate the friction stir welding (FSW) process using the Ansys Mechanical Application. To see this example solved using Ansys Mechanical APDL see Friction Stir Welding (FSW) Simulation in the Technology Showcase: Example Problems. Several characteristics of FSW are presented, including tool-workpiece surface interaction, heat generation due to friction, and plastic deformation. A nonlinear direct coupled-field analysis is performed, as thermal and mechanical behaviors are mutually dependent and coupled together during the FSW process.
Because it is often difficult to find a full set of engineering data to simulate the FSW process, the problem emphasizes the simulation rather than the numerical results. A simplified version of the model created by Zhu and Chao [1] illustrates the FSW simulation method.
The following features and capabilities are highlighted:
Direct structural-thermal analysis using coupled-field solid elements
Plastic heat generation in coupled-field elements
Frictional heat generation using contact elements
Contact elements with bonding capability
