Abstract

This paper discusses causes and consequences of plastic deformation of packaging sheets which are nowadays used in a wide range of applications. The article deals with a specific inhomogeneity and localization of plastic deformation which is analysed in detail. For material testing, uniaxial and biaxial tensile test was used and the results were also compared and evaluated. In the last part of this paper microstructure of material was analysed by localized deformations.

Keywords
