Use of FEM in the Drawing Die Structure Design

The Finite Element Method is a widely applied tool for solving structural mechanics problems. The present paper illustrates the advantages related to the use of the F.E. analysis in the sheet metal die construction activity. Since punch, die and blankholder can be represented by finite element models, the die structure deflection and stress induced by loading conditions can be predicted. This capability allows achieving some actual advantages, considering that the technological development supplies the engineers with hardware and software instruments able to analyze in short time large problems. Numerical computation activities allow to foresee possible inconveniences which could occur during the construction by using only virtual models, before physical parts being made.
