ABSTRACT
The major manufacturing strategy for constructing bodies of automotive and aerospace structures is sheet metal forming. It involves a cluster of significant manufacturing processes from simple bending to deep drawing. A wide range of products from body panels, fenders, and wing parts to consumer products like kitchen sinks, cans, and boxes are made with precision through different operations on a plane blank. One of the most significant operations is the forming process, which is also termed drawing/stamping. Finite element methods play a very important role in reducing cost as well as time to obtain a complex physical phenomenon, and also help to better understand the process and to control the quality of the product. Thus, numerical simulation of the sheet metal forming process is a very useful tool for analysis. Formability is concerned with sheet metal forming. Most sheet metal operations involve extensive tensile deformation.
