RESUMO

The metal forming processes have extensive industrial application although their projects are based mainly in experimental techniques. With the development of more powerful computers, the use of numerical methods to design, simulate and optimize costs of such processes has become possible. Among the numerical methods, the Finite Element Method have large application in forming simulation, since it allows the prediction of the material flow during the sheet metal forming process. Ideal blank shape is that one which produces a part with constant flange, minimizing or eliminating trimming operations. In order to determine the ideal blank shape, this work developed a methodology to blank shape optimization. This optimization methodology has been integrated to a commercial Finite Element analysis software, the ANSYS/LS-Dyna3D. The results applied to a simulation of a square cup part are showed and discussed in order to validate the proposed optimization methodology.
