TLDR
In this paper, an exact elastic-plastic solution for the stresses in a flat ring subject to pressure is obtained on the basis of J2 deformation theory together with a modified Ramberg-Osgood law.Abstract:
An exact elastic-plastic solution for the stresses in a flat ring subject to pressure is obtained on the basis ofJ2 deformation theory together with a modified Ramberg-Osgood law. The results are assessed on the basis of Budiansky's criterion for the acceptability ofJ2 deformation theory. By using exact elastic-plastic stresses, the radial enlargement and the permanent increase in thickness of the ring at the hole are obtained. Upon release of the pressure, residual stresses are produced around the hole.read more

An exact elasto-plastic solution for an open-ended thick-walled cylinder of a strain-hardening material
TL;DR: In this paper, a closed-form analytical solution for the elasto-plastic stress, strain, and displacement components of an internally pressurized open-ended thick-walled cylinder made of a strain-hardening material is obtained by using the deformation theory of Hencky and the yield criterion of Von Mises and choosing stress components as basic unknowns.

Rajkumar Shufen,Uday S. Dixit +1 more
TL;DR: Autofrettage is a metal forming technique widely incorporated for strengthening the thick-walled cylindrical and spherical pressure vessels as mentioned in this paper, which can be classified into hydraulic, swage, explosive, thermal, and rotational.

Analytical Modeling in Deformation Analysis of Interference-Fit Structures
TL;DR: In this paper, the authors applied the decohesive carrying capacity criterion based on the radial strain analysis of double-shear riveted or bolted joints, where the material of the plate is considered to be elastic-perfectly-plastic obeying the Huber-Mises-Hencky yield criterion.
