Rupture dynamics of shock-tube diaphragm

Diaphragm rupture process in a shock tube was studied through transient simulations. With the help of ANSYS Explicit Dynamics, the rupture process occurring in a shock-tube was simulated. Diaphragms of several thicknesses and scores were analysed. It was possible to predict the pressure difference at which rupture would take place which would help in bring down the cost and time required to setup and carry out experiments in a shock-tube. Experiments has been carried out in a shock tube to validate the simulations results and compared with simulation data.
