A Study of Thickness Change of Spherical Cup Made from TRIP Steel after Hydraulic Bulge Test

Abstract:

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.
