whereP, the internal pressure;t, the wall thickness;r, the radius of the cylinder. The SI unit forPis Pascal, whiletandrare in meters. If the pipe is closed on the ends, any force applied to them by internal pressure will induce anaxial orlongitudinal stress(σl) on the same pipe wal...
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 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 ...
For this reason the attention in this section is focused on the effective axial stress, detailing available methods for axial stress calculation. Following the works of Refs. [9] and [10], the induced effective tension, Teff, can be related to the axial tension (true wall tension), Ttw, ...
Relations between crack opening displacement and hoop stress in zircaloy-2 pressure tubes containing axial defects Analysis of the end-of-slit opening measurements in Zircaloy-2 pressure tubes containing axial through-the-wall defects as a function of hoop stress has shown that the experimental data ...
Finally an approximate formula with high precision is proposed to evaluate the stress intensity factor along the axial crack front in the hoop wrapped cylinder with composite layer.Jianjun ChenHongliang PanInternational Conference on Pressure Vessel Technology...

The method enables the stress in the end slabs resulting from internal excess pressure to be compensated without special arrangements in these slabs. By increasing the hoop prestressing towards the ends, the inertia axis of the respective slab is displaced towards the axial centre of the vessel. ...
