Abstract
Rolling force and torque are often measured during the rolling process and their magnitudes used in the process control algorithms. Slab, upper bound and rigid-plastic finite element methods have been applied for predicting force and torque in rolling. This paper compares the results of these methods and that of DEFEL (an elastic-plastic finite element code) with experimental data. It is concluded that slab and upper bound results are very approximate. The rigid-plastic finite element method is fairly accurate for low

(roll radius by sheet half thickness) ratios. However, for large
