بارك الله فيك

Merci beaucoup

Why are you using coefficient of friction for Resistance Spot welding

Thank you this very interesting, What if you want to add different properties for the weld and HAZ? It could be the same model just assign different material properties for each zone or part

Please share a simulation on FSSW (friction stir spot welding) system abaqus step by step and send me the CAE FSSW file

A complete waste of time.
