Effect of strain rate on flow stress and anisotropy of DP600, TRIP780, and AA5182-O sheet metal alloys

This paper presents the results of an investigation into the rate sensitivity of DP600, TRIP780 and AA5182-O sheet metal alloys. The effect of strain rate on both the flow stress and anisotropy characteristics was also examined. Tensile experiments were performed at room temperature under conditions ranging from quasi-static to high strain rate loading on the three alloys in three orientations (0°, 45°, and 90°) with respect to the rolling...
