As one of the protecting devices on the equipment of petrochemical and chemical industries, dished rupture-disc has been used Widely. In the application of rupturedisc, it is of great importance to calculate the bursting pressure of the membrane accurately. In literature, most of the previous authors proposed to base the calculation upon the true stresses or experimental data of the membrane material, which is rather troublesome or inaccurate. in this paper, an engineering calculating method is proposed to evaluate the bursting pressure with the ultimate tensile strength and strain of the material used, which is more simple and accurate.

Based upon stress measurements and results of bursting test and used theprogramme of axi-symmetric finite element with particular reference to the largeplastic deformation, the elastic-plastic stress in a thick-walled spherical accumulatorwith a nozzle was calculated. The stress distribution, location of maximum stressand stress concentration factor at the junction of the nozzle with the sphere underload were analyzed. According to Von-Mises yield criterion, the pressure for localyielding at the janction was calculated, as well as the pressures for general yieldingat the junction and the general yielding sperical shell. The dilation of plastic yieldingzone at the junction and the spherical shell was further analyzed. The stressdistributions and stress concentration factors in the elastic-plastic stage and the plasticstage of the structure were also analysed. The results of theoretical stress calculations were compared with the results ofthe bursting test of the vessel. The failure mechanism of thick-walled sphericalpressure vessels and the methods of calculation of the bursting pressure werediscussed,
