Preface: This isn't an actual project, just trying to get the design to be realistic for a 3D model in a video game. I know most pressure vessels are round and the overall shape of this one would be round, but it's very large (about half a football field large) so it would be composed of a bunch of panels. The 4'x8'x1' piece of glass would be supported evenly on all four 1'-wide sides by being clamped into a support 1.5 inches deep (so the actual surface area would be 45"x93"). Would this be good enough to hold 60psi (actually 1atm, but from what I've read about double the pressure is a good design parameter to go by)? What would be the maximum pressure of this design? Does anyone happen to have the equations for a calculating the maximum pressure allowable for flat panels like this so I might plug different materials into the equations?
