Influence of Tension-Compression Anomaly During Bending of Magnesium Alloy AZ31
Publication date: Available online 18 August 2017 Source:Materials Science and Engineering: A Author(s): Sebastian Härtel, Marcel Graf, Thomas Lehmann, Madlen Ullmann In this paper, the influence of the tension-compression anomaly of magnesium alloys on the numerical accuracy is quantified for the first time. For this, flow curves were evaluated for a twin-roll cast, rolled and annealed AZ31 strip using tensile and compression tests at different temperatures and constant strain rate. This is necessary to take into account the changing material behavior under tensional and compression load within the FEM. To quantify the ...
