Numerical Analysis of Circular Pre-notched U-Channel Section Distortions in Cold Roll-Forming Process [PDF]
International Journal of Advanced Design and Manufacturing Technology, 2017 Cold roll forming is a process in which a metal sheet gets a desired section form by passing through a series of rotating rollers. Predicting the amount of the distortion in pre-notched cold formed sections still remains challenging in cold roll forming ...
