Abstract
This study uses the three dimensional finite element code to examine the plastic deformation behavior of internal void defects at the roll gap during the shape rolling of V-sectioned sheets. The finite element code incorporates the rigid-plastic model. The rolls are assumed to be rigid bodies and the temperature change induced during rolling is ignored. The analytical model is employed to conduct a systematic examination of the filling ratio at the roll gap, the spread ratio of the sheet, the rolling force, the principal strain, the mean stress, and the variation of the void dimension at the exit under rolling conditions characterized by different roll profile inclinations, roll radii, and thickness reductions, etc. The results of the analysis can be used to stabilize finite element software to form the shape rolling of sheets with internal void.
