WebMar 26, 2016 · For spherical pressure vessels, use the following formula: Bending stresses: For symmetric cross sections in the XY plane, use this formula: (moment about the x -axis) (moment about the y -axis) Flexural shear stresses: Here's the formula for calculating flexural shear stress: Torsional shear stress: Use this formula to find torsional shear stress: For the thin-walled assumption to be valid, the vessel must have a wall thickness of no more than about one-tenth (often cited as Diameter / t > 20) of its radius. This allows for treating the wall as a surface, and subsequently using the Young–Laplace equation for estimating the hoop stress created by an internal pressure on a thin-walled cylindrical pressure vessel: (for a cylinder) For the thin-walled assumption to be valid, the vessel must have a wall thickness of no more than about one-tenth (often cited as Diameter / t > 20) of its radius. This allows for treating the wall as a surface, and subsequently using the Young–Laplace equation for estimating the hoop stress created by an internal pressure on a thin-walled cylindrical pressure vessel: (for a cylinder) see med tancredi
