WebIt is natural to align one coordinate along the axis of the vessel (i.e. in the longitudinal direction). To analyze the stress state in the vessel wall, a second coordinate is then aligned along the hoop direction. With this … WebThis tangential stress accounts for the stress in the plane of the surface of the sphere. The stress normal to the walls of the sphere is called the radial stress, r. The radial stress is …

Pressure Vessel, Thin Wall Hoop and Longitudinal Stresses

WebSolving for the hoop stress we obtain: h pr t σ= In summary we have: Longitudinal Stress l 2 pr t σ= Hoop Stress h pr t σ= Note: The above formulas are good for thin-walled pressure vessels. Generally, a pressure vessel is considered to be "thin-walled" if its radius r is larger than 5 times its wall thickness t (r > 5t).
