friction stir welding

[pradhanks]

I'm trying to simulate FSW. Currently I'm facing problem with the translation of the tool. Tool is rotating but not translating even though I have input the translation velocity. Also how do you simulate plunge stage??

Hello,
I'm also trying to simulate a friction based welding process and facing problems in analysis. Can I know if you've run the analysis and if yes have you faced the problem of excessive distortion of meshing. If so, how did you overcome the problem ?

and a possible solution to your problem, is to define the tool as a rigid body and give it motion by using velocity/angular velocity in the same module and giving it an appropriate amplitude.
