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....
ASME Pressure Vessel Design and Engineering ASME SECTION VIII - Thin Cylindrical Shells: Equations and Calculator: The formulae in ASME Section VIII, Division 1, paragraph UG-27, used for calculating the wall thickness and design pressure of thin wall pressure vessels, are: a) Circumferential Str...
PURPOSE: To embody the stress reduction welding structure of a pressure vessel being excellent in the economics, by which a local bending stress is scarcely developed in weld zones of each shell, respectively in end plate structures of both ends, and accordingly, plate thickness of each shell ...

This book guides through general and fundamental problems of pressure vessel design. It moreover considers problems which seem to be of lower importance but which turn out to be crucial in the design phase. The basic approach is rigorously scientific with a complete theoretical development of the ...
As an application of the foregoing equations, consider the optimal structure for the end closure of the pressure vessel shown in Fig. 4.14. The cylindrical part of the vessel consists of a ±ϕR angle-ply layer with thickness hR that can be found from Eq. (12.76) in which we should ta...
The development of a Pressure Vessel Nozzle Local Stress Prediction Software based on ABAQUS-Machine Learning has positively impacted several aspects as follows: 5. Conclusions Through a Pressure Vessel Local Stress Prediction Software based on ABAQUS and machine learning, users can swiftly input geometri...
The Pressure Vessel Design study combines the results of the static studies algebraically using a linear combination or the square root of the sum of the squares (SRSS). When using a solid mesh, the software provides a stress linearization tool to separate bending and membrane components. ...
When the cylindrical shell is subjected to the internal pressure P, the average components of the nominal stress in the circumferential, axial and radial directions, acting on the surfaces of the elementary volume containing the cavity (Figure 4b), can be expressed using the below Lame equations,...
During the study, some concepts and parameters were proposed to represent pressure pulsations, namely peak-to-peak value Δpp-p, amplitude Δpa = 1/2Δpp-p and RMS amplitude as seen in Equations (14) and (15). Moreover, the dimensionless treatment for pressure amplitude was also introduced...
