SANTOS, Abel D  e  TEIXEIRA, Pedro. Experimental Reference Geometries and Numerical Modeling in Sheet Metal Forming Processes. Inf. tecnol. [online]. 2006, vol.17, n.5, pp.51-54. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642006000500008.

This paper presents experimental reference geometries to be used in sheet metal forming. Each reference geometry attempts to model the  typical behavior of pieces of sheet metal. The results of this study were compared with  data obtained from the literature. Discussion is also presented on aspects related to the reproducibility and reliability of the results.  Sliding  of the blank over the punch, and the press ram speed are important in this reproducibility. Finally, numerical simulations are presented for one of the reference geometries presented, using finite elements. The results are compared with experimental results, demonstrating  good correlation between them.

Palavras-chave : reference geometries; numerical modeling; finite elements; sheet metal forming.
