Accuracy of Flange Width of Flexible Channel Section Formed by Flexible Cold-Roll Forming Machine

investigating the effect of geometric parameters on the twist angle in roll-forming of non-symmetric channel section, using finite element simulation

cold roll-forming is a process in which the roll of sheet is formed by passing continuously through the set of rotary rollers without changing thickness in a cool way until it is formed to the desired profile. in this paper a parametric study on the section twist angle in roll-forming the non-symmetric channel is presented, using finite element simulation. at first finite element simulation res...

Stress Analysis and Energy Estimation in Cold-Roll Forming Process

In this article, stress analysis and energy estimation during cold-roll forming of symmetrical channel sections have been discussed. Geometry of sheet strip is pre-estimated by a shape function. Then longitudinal, transversal and shear strains have been calculated. Using both the Levy-Mises and the Prandtl Reuss equations, and also considering the Bauschinger effect, stress distributions have b...

Investigation of the mechanical properties of cold roll welded Brass and IF steelproduced by cold roll bonding process

Cold roll bonding (CRB) is a solid state welding process, where the bonding is established by compressive plastic deformation of the metals. This process is applicable for a large number of materials. In addition, materials that cannot be bonded by traditional fusion-based processesmight be bonded by CRB process. In this research, cold roll welding of brass and IF steel was studied .The effects...
