Description: In the hydraulic bulge test, a sheet metal test specimen is bulged by a hydraulic medium. The geometry of the bulged test specimen is defined by the geometry of the bulge die. In many cases the flow curve obtained from this experiment deviates considerably from that obtained by tensile tests. This deviation may be caused by the normal anisotropy of the sheet. This interactive animation schematically presents the hydraulic bulge test, and flow curve for Al -Cu 7-12-2-2 alloy is obtained.
