I have a simple three part assembly. It is essentially a hollow cylinder, a top and a bottom. The space inside the cylinder assembly will increase in pressure instantaneously and the top will shear releasing the contents of the cylinder.

I have been tasked with determining what the pressure will be when the top shears. I can, and have, done the calculation with pen and paper, but I need a SW analysis as well.

I can use SW Simulation to fix the top piece in space and apply a pressure, but not the other way around.

How can I determine the pressure at which the top piece of my assembly shears?
