Abstract

Rupture discs are used as high speed valves in GAS GUNs to study impact and penetration phenomena. These devices are also used extensively in SHOCK TUNNELs for the study of explosion and shock waves. In the article grooved and ungrooved RUPTURE DISCs are studied numerically as well as experimentally in order to design an Aluminum diaphragm to be used in a GAS GUN. INSTABILITY and rupture analysis of discs is the main concern in this paper. LS-DYNA software has been used in order to simulate deformation and rupture phenomena. A tester and several diaphragms were constructed and tested in order to empirically determine rupture pressure. Rupture pressure were measured experimentally for ungrooved and GROOVED DIAPHRAGM with 1mm depth. Using experimental data, a semi-empirical relation is developed which delivered approximate rupture pressure for grooved and ungrooved diaphragm. The results of the numerical and experimental investigations were compared and good agreements were obtained.
