WebJan 22, 2024 · If you want to understand failure, you'd consider all types of stress (normal and shear stresses) and the use some failure theory (Tresca, Von Mises etc) to determine if failure occurs. If you are worried about buckling you'd need to carry out a different type of analysis.

In mechanics, a cylinder stress is a stress distribution with rotational symmetry; that is, which remains unchanged if the stressed object is rotated about some fixed axis. Cylinder stress patterns include: circumferential stress, or hoop stress, a normal stress in the tangential (azimuth) direction.axial … See more Hoop stress The hoop stress is the force over area exerted circumferentially (perpendicular to the axis and the radius of the object) in both directions on every particle in the cylinder wall. It can … See more The first theoretical analysis of the stress in cylinders was developed by the mid-19th century engineer William Fairbairn, assisted by his … See more Thin-walled assumption For the thin-walled assumption to be valid, the vessel must have a wall thickness of no more than about … See more Engineering Fracture is governed by the hoop stress in the absence of other external loads since it is the largest principal stress.
