1. Numerical Simulation of Ultrasonic Assisted Indentation Tube Forming

Saeid Dashti; Masih Paknejad; Amir Abdullah; Abbas Pak

Volume 13, Issue 3 , September 2020, Pages 1-8


  Indentation forming is an internal tube forming process in which a mandrel with a diameter slightly larger than that of the tube is pressed inside the tube and in so doing, creates the internal profile. Forming forces have a significant effect on the spring back, residual stress, quality of the inner ...  Read More
