Effect of initial sheet thickness on shear deformation in ferritic rollingof IF-steel sheets

The effect of sheet thickness an shear deformation and texture for the ferr ite rolling has been studied. The shear deformation was estimated from the distorted shape of inserted wire before rolling and FEM simulation. The def ormed shape of inserted wires and FEM results showed that the shear strain decreased with increasing initial sheet thickness. The measured and simulat ed textures also showed that the Goss component changed to Dillamore compon ent as the thickness increased. From rolling simulation of 20% reduction, t he minimum shear deformation was found to exist for the given roll bite geo metry and friction coefficient.
