Abstract
The enhancement of material modeling in fields of sheet metal forming is essential for finite element-based designing of processes and dimensioning of parts. Since new lightweight materials, e.g. aluminum and magnesium wrought alloys show anisotropic and temperature-dependent forming behavior adequate testing methods and evaluation strategies have to be developed to obtain the reliable material data. For that purpose an experimental setup has been designed at the Chair of Manufacturing Technology which enables biaxial tensile testing of sheet metal at elevated temperatures. In this paper, the setup is introduced and the obtained results, i.e. experimentally determined yield loci and subsequent yield loci as a function of temperature are given for the well-known aluminum alloy AA6016 as well as the magnesium alloy AZ31.
