Metal forming is one of the important manufacturing processes. There are three types of metal forming processes: bulk metal forming, sheet metal forming, and sheet-bulk metal forming. Some popular metal forming processes are forging, rolling, wire drawing, extrusion, deep drawing, and bending. Engineers are interested in the estimation of forming load and product quality in metal forming. Various modeling techniques have been employed for this purpose, for example, slab method, slip line field method, visioplasticity, upper bound method, finite difference method, and finite element method.
