<p>Rupture disk devices are non-reclosing pressure relief mechanisms employed to safeguard vessels, pipelines, and other pressure-containing components from high pressure and/or vacuum conditions. The rupture disk is also a load rate- sensitive device. Burst pressures can vary significantly with the applied pressure rate on the rupture disk device. In this study, two types of disks were manufactured using hydroforming (HF) and deep drawing (DD) processes, and the effect of load rates was investigated on burst pressure and bulge height of hydroformed and deep drawn rupture disks. First, the HF and DD processes were applied to form the rupture disks. Second, the burst of the disks was done using a waterjet machine and then simulated by ABAQUS software. The Gurson-Tvergaard-Needlemann (GTN) criterion was used to determine the parameters defining the damage in software. After validation of simulation results, the effect of load rates was investigated on the bulge height and burst pressure of HF and DD rupture disks.</p>
