Abstract

In this paper, an alternative solution to Haşek method, named conventional, for forming limit curves determination is proposed. New types of samples, for the experimental research, were used, which dimensions are reduced three times in comparison with the conventional ones. These samples were used for a thicker material. The experimental work assumed the manufacturing of a new dies, for cutting and forming, the manufacturing of the new sample and a lot of experimental tests. The obtained results are in concordance with the ones that correspond to conventional method. Next improving, in control of the material restraint and binder force, must be considered for refining the results.
