Service failures of pressure vessels are generally a consequence of inherent part-through surface of sub-surface defects. The catastrophic pressure vessel failures of the mid 50's and 60's necessitated the development of a technology for the understanding and thereby eventual elimination of these ...
Thin-walled pressure vessels are one of the most typical applications of plane stress. Consider a spherical pressure vessel with radius r and wall thickness t subjected to an internal gage pressure p. For reasons of symmetry, all four normal stresses on a small stress element in the wall ...
In comparison, the thick-walled cylinders were 483.9 bar for 5-unit cells pattern and 520.6 bar for 1-unit cell pattern. According to the data, it can be inferred that winding pattern had no significant effect on the implosion pressure of the filament-wound cylinders. Failure of ...
One can also get a sense of how small this load is by a simple mechanical thought experiment: Suppose the tube were not an origami but instead a homogenous thin-walled cylinder. Then, due to force balance, an internal pressure \(p\) as above would generate a hoop stress \(\sigma \sim...
Then, dynamic response simulation of superalloy thin-walled structure under the same load as experiment was implemented, and fatigue life was estimated based on the fatigue life prediction model which mainly included: improved rain-flow counting method, Morrow average stress model and Miner linear ...
limiting pressure鈥擳he failure criteria and limit states for thin-walled pressure vessels are analyzed taking into account the influence of plastic deformations. The introduction describes the main problems in operation of thin-walled vessels working under internal excess pressure associated with ...
Thin-walled shellHigh pressureLaplace'S lawAnalytical solutionThe problems of the general corrosion of pressure vessels have been investigated by a number of scientists using the law of P.-S.Laplace for thin shells. However, the existing solutions based on Laplace's law provide satisfactory ...
