Granična deformabilnost pri višefaznom dubokom izvlačenju

Abstract

The use of classic and new materials in technologies of plastic metal forming represent the reliable definning of formability parameters. At deep drawing of thin sheet metals the aspect of formability is most certainly one of the most important and most investigated aspects. The paper carries on the analysis of additional operations of deep drawing which are realized by standard and opposite-direction procedure, and gives the results of experimental researches. The paper shows the dependencies of forming force on travel, strain distributions, and also shows the relations in forming limit diagram.
