When is calculated the punching force is taken into account only the perimeter and not its form. In this case, the pressing force for the contours with the same length, but with different geometries (circle, square, hexagon, triangle and shearing) may have different values. To demonstrate this hypothesis were made experimental tests and they confirm this supposition. Now this hypothesis is verified using the finite element analysis in order to show the possible differences and to view the material behavior during punching process. The analyzed materials are AISI 304, DC01 (AISI 1008), Al99.8 and Brass CDA 110. The software used to make the finite element analysis is Deform 3D version 6.1 (service pack 2).
