| Abstract: | Strip rolling is simulated using an elastic-plastic finite element technique which includes the extent of both elastic and plastic deformation outside the nominal contact deformation zone. Solutions for non-steady and steady-state rolling are obtained. The stress and strain distributions within the workpiece, the velocity fields (absolute and relative to the roll surface), and the normal pressure and shear stress distributions along the arc of contact are calculated. Analyses are conducted with different levels of friction, material properties, workpiece dimensions and reductions. The results are compared with previous theoretical and experimental work, with which good agreement is found. The usefulness of numerical analyses for the investigation of parameters relevant to industrial rolling practice is demonstrated. |
