Abstract
The present theme of research proposes the elaboration of a technical solution for reduction or elimination of instability phenomena effect based on the study of blank holder force variation as a function of part configuration and different efforts that stress the material in different zones of the part. The article presented structure of hydraulic research equipment used to the metal sheets deformation, constructive and functional parameters and aspects concerning the influence of blank holder force on the intensity of instability phenomena.
