Using the geometry of figure 1 axial stress (σa) is given by: Axial Stress Formula: σt= ( pir2i) / ( r2o- r2i) pi= internal pressure (psi, MPa), ri= inside radius (in, m), ro= external radius (in, m) Related: Thick Walled Cylinder Stress Pressure Vessel Equations and Cal...
The paper deals with elastic–plastic analysis of the stress–strain state in the vicinity of a hole in a thick-walled cylindrical pressure vessel. The investigations have been inspired by the phenomenon of ductile fracture observed in a high-pressure reactor. Using finite element calculations, diff...
Equations are developed for prediction of steady-state creep stresses and strain rates in a thick-walled tube under combined internal pressure and axial load. An analytical solution of the equations, in closed form, is not possible but numerical solutions to the equations are tabulated for various...

The purpose of this paper is to investigate the effect of stress classification on cyclic viscoplastic response of a structure (here, a thick spherical vessel which has an application in pressure vessel technology). The response is either reverse plasticity and shakedown or ratcheting behavior of a...
Stress analysis of an autofrettaged thick-walled pressure vessel containing an external groove and subjected to internal pressure is described. From the equivalence of thermal and autofrettage residual stress fields, the autofrettage residual stress distributions of the external grooved thick-walled pressure...
