This article presents an overview of recent progresses in experimental investigation and
finite element analysis (FEA) of ratcheting behavior of pressurized piping. Ratcheting …

This study determines the plastic, shakedown and elastic limit loads and the corresponding
regimes of 90° pressurized pipe bends with shape imperfections subjected to cyclic in-plane …

Many pressure vessel and piping components have to withstand high internal pressures and
are therefore thick-walled so that geometric effects such as stress stiffening need not be …

Abstract The Linear Matching Method is used to create the shakedown limit and limit load
interaction curves of 90° pipe bends for a range of bend factors. Two load cases are …

No experimental data exist within open literature, to the best knowledge of the author, for
determining shakedown boundaries of 90° back-to-back pipe bends. Ninety degree back-to …

The present work quantifies the effect of ovality and wall thinning on plastic, shakedown and
elastic limit load of pipe bends under cyclic in-plane closing bending load and internal …

Plastic collapse loads of 90° pipe bends with structural defects subjected to in-plane closing
bending are systematically examined in this study using three dimensional nonlinear finite …

The elbows play a critical role in industrial and power plant systems. To ensure operational
safety, extensive research has been conducted on the fatigue behaviour of pipe bends. This …

The present study determines the effect of shape imperfections on the B 2 index of pipe
bends subjected to in-plane opening moment using 3D nonlinear finite element (FE) …

Purpose The purpose of this study is to investigate the effect of structural deformations and
bend angle on plastic collapse load of pipe bends under an in-plane closing bending …
