Longitudinal Stress Thin Walled Pressure Vessel:When the vessel has closed ends the internal pressure acts on them to develop a force along the axis of the cylinder. This is known as the axial or longitudinal stress and is usually less than the hoop stress....
Stress AnalysisThin-Walled Pressure VesselThis paper discusses the stresses developed in a thin-walled pressure vessels. Pressure vessels (cylindrical or spherical) are designed to hold gases or liquids at a pressure substantially higher than the ambient pressure. Equations of static equilibrium along wi...

Thin-walled structures are typically designed to ensure that the hoop stress does not exceed the material's allowable stress or yield strength to prevent failure due to excessive pressure. In contrast to hoop stress, there is also longitudinal stress (axial stress) in such structures, which acts ...
According to Newton's first law of motion, the hoop stress yields, Remarks • 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 > 5 · t). ...

Variations were implied to the winding angle of the helical winding: ±30°,±45°,±60°±30°,±45°,±60° and the hoop winding was 90°90° . The specimens were built with average R/t ratio = 18.8, which can be categorized as relatively thick-walled cylindrical shell. The nominal...
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...
