Shock waves are one of the primary cause for brain injury during wars. This has significant effect on skull deformation thereby causing the injury to brain. This thesis work is done to observe the effects of skull deformation by replicating it with a fluid filled cylinder and exposing it to different incident blast over-pressures. Here our primary interest is how the pressure varies inside the cylinder along with the flow of shock wave around the cylinders of different thicknesses. This will help us understand pressure variance inside brain due to deformation along with transmitted wave.
