In contrast to hoop stress, there is also longitudinal stress (axial stress) in such structures, which acts along the length of the cylinder or sphere. The calculation for longitudinal stress is different from that of hoop stress. Thin-walled structures are commonly found in applications like pre...
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....

Thin Walled Sphere Stress Pressure Vessel Equations and Calculator Thin-walled vessels are typically either spherical or cylindrical. Other geometries are possible, but their complexity precludes their inclusion in this webpage. Pressure vessels can be considered thin if the diameter is greater than ten...
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...
carried out on the high-temperature stretching arc-shaped test sample of the thin walled tube, the transitional circular arcs do not generate overlarge stress concentration, thereby avoiding the abnormal breakage of the test sample in the high-temperature stretching process due to the stress ...
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...
Question: A thin-walled cylindrical tank, under internal pressure p, is compressed by a force F=115kN, as shown in the diagram below. The cylinder diameter is d=90mm and the wall thickness is t=5.5mm. The allowable normal str...
Fig. 1. Schematic diagram of RDB and typical stress/strain distributions of tube materials Up to now, many efforts have been done on the effects of processing parameters on the bending behaviors in thin-walled tube bending. WU et al [4] experimentally studied the influences of temperature, ben...
