A simplified three-dimensional method for simulating plastic deformation in roll forming of wheel rims with grooved rolls is developed on the basis of the rigid-plastic finite element method using generalized plane-strain modeling. In this method, the roll forming process is approximated as a forging process with dies having the same cross-sectional shapes as the grooved rolls, and the elongation in the hoop direction is kept uniform in the cross-section. The effects of the shear deformation in the hoop direction and the constrain of the elongation in the hoop direction due to the material outside the roll gap are taken into consideration. The calculated shapes of formed rims are in good agreement with the experimental ones for a 1/5 size of the actual products.
