Introduction
Nowadays, in the modern industry, the deep drawing process is used extensively; however, it is still based on experimental methods and very expensive. The plastic forming of sheet metals is the production of certain material under the right conditions, such as suitable stress rate, and low pressure without wrinkles and creases. In 1997, Mamalis has investigated the deep drawing of cylindrical boxes with the effect of forming characteristic of the material simulation using the explicit finite elements method (with the help of DYNA 3D program). The punching force, by changing the punch movement distance, extension dependent theoretical results of five different galvanized and aluminum sheet plates (radial, peripheral and along its thickness) were compared with experimental results and good consistency is observed
