The effects of forming parameters in the roll-forming of a channel section with an outer edge

A B-spline finite strip method was employed to investigate the influence of forming parameters such as bend angle increment, strip thickness, material yield limit, outer edge width, web width and distance between two roll stations on the peak longitudinal membrane strain developed in the cold roll-forming of a channel section with an outer edge. The peak longitudinal membrane strain increases with the bend angle increment, the strip thickness and the material yield limit increase, but decreases with the outer edge width, the web width and increase of the distance between two roll stations. The results from the study are consistent with the phenomena observed in the previous study of the roll-forming process.
