摘要：

Based on the slab method analysis, a new solution for asymmetrical rolling of unbonded clad sheet is presented in this paper. The non-uniformity of the shear stresses and the uniformity of the normal stresses at the vertical sides of each slab across the portion of the deforming.material all over the plastic region are considered. The effects of the process parameters such as reduction, work rolls radii ratio and work rolls speed ratio on process outputs are investigated. In addition, the asymmetrical clad sheet unbonded before rolling process is simulated wholly using ABAQUS/explicit software. Comparisons of analytical results from present model with those from experimental studies of the other investigators and the finite element simulation have showed good agreements.
