Abstract

The main instability phenomena that occur in plastic forming of metal sheets are springback and wrinkling. These phenomena lead to the decrease of the working accuracy by modifying the geometric shape of parts and worsening their surface quality. The present paper presents the technical methods applied to prevent or to eliminate the effects of these phenomena
