The article deals with the comparison of thickness change of spherical cup made from TRIP steel RAK40/70 after hydraulic bulge test. The thickness has been measured by timing gauge and by apparatus Argus. Experimental material thickness has been 0.75 mm. From measured values of thickness of experimental material has been calculated the dependence stress-strain by models of several authors.

Two Parameters

The paper describes a new experimental procedure for the determination of the curves relating the equivalent stress and equivalent strain of sheet metals by means of the hydraulic bulge tests through elliptical dies. The procedure is based on an analytical model of the bulging process and involves the measurement of only two parameters (pressure acting on the surface of the specimen and polar deflection).
