Autofrettage is a metal forming technique widely incorporated for strengthening the thick-
walled cylindrical and spherical pressure vessels. The technique is based on the principle of …

A numerical method based on the extension of the variable material property method was
developed to obtain the elasto-plastic stress field in a functionally graded (FG) rotating disk …

This paper provides a critical review of the advancements made in the application of the
variable material properties (VMP) method over the past two decades. The VMP method was …

This paper focuses on high-strength and hardness steels which are used as an upgraded
material in the construction of high-pressure vessels. Their mechanical behavior shows that …

The new approach introduced for the autofrettage called the rotational autofrettage is
applied here for thick-walled cylinders made of materials with linear strain hardening …

In this study, residual stress distributions in autofrettaged homogenous spherical pressure
vessels subjected to different autofrettage pressures are evaluated. Results are obtained by …

Residual thermal stresses are formed in dental restorations during cooling from high
temperature processing. The aim of this study was to evaluate the influence of constructive …

Stress intensity factors for internal surface cracks in autofrettaged functionally graded
cylinders have been studied. It is assumed that the mechanical properties change with a …

In this paper, elastoplastic buckling behaviors of functionally graded material cylindrical
shells under axial compression are investigated with Donnell shell theory and J 2 flow …

The residual compressive stresses induced by the autofrettage process in a metal vessel are
limited by metal plasticity. Here we showed that the autofrettage of layered metal–ceramic …
