WebOct 1, 1999 · The proposed hollow cylinder test is shown to be able to follow any designed stress paths in the principal stress space. Thus, it may be used to investigate the effect of stress paths on the mechanical behavior of rock and to construct its failure surface. Keywords Sandstone Stress–strain relationship Failure surface Stress path 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 stress, a normal stress … 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 mathematical analyst Eaton Hodgkinson. Their first interest was in studying the design and failures of steam boilers. … 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 one-tenth (often cited as Diameter / t > … See more Engineering Fracture is governed by the hoop stress in the absence of other external loads since it is the largest principal stress.
