Resumo (PT): In the last few years, the sheet metal forming operations have undergone considerable advances. On one hand computational methods for predicting material processing defects have been developed. On the other hand, the knowledge of physical mechanisms occurring during plastic deformation allows the precise description of the material constitutive laws. The aim of this paper is to attempt to clarify the "microscopical-macroscopical" transfer in metal sheets submitted to complex strain histories.
