Analyzing Effect of Friction on Spread and Budge in Flat Rolling by FEM Method

In this research a final element model for simulating three dimensional deformation in rolling of flat product is modeling in ABAQUS and further developed to study the frictional effects on spread and bulge. To predict the magnitude of bulging , the rolling process is approximated by successive forging steps. The elongation or the average spread at each step from the previous calculations are used in the model. The theoretical results of the model is in a good agreement with the experimental values given by other investigation.
