Thin Walled Pressure Vessel - SKYSCRAPERS
priodeep.weebly.comWhen analyzing thin walled pressure vessels it is assumed that all stresses act parallel to the surface of the vessel. This is often called "membrane action". In the cylinder below, the only stress acting on the cut which can counteract the internal pressure is the normal stress σ2.
