Buckling Analysis and Structure Improvement for the Afterburner Cylinder of an Aero-Engine

open access: yesAerospace, 2023
The buckling failure of the afterburner cylinder is a serious safety concern for aero-engines. To tackle this issue, the buckling simulation analysis of the afterburner cylinder was carried out by using finite element method (FEM) software to obtain the ...

Numerical Simulation of Buckling and Post-Buckling Behavior of a Central Notched Thin Aluminum Foil with Nonlinearity in Consideration

open access: yesMetals, 2020
In thin notched sheets under tensile loading, wrinkling appears on the sheet surface, specifically around the cracked area. This is due to local buckling and compression stresses near the crack surfaces.

Numerical research on the lateral global buckling characteristics of a high temperature and pressure pipeline with two initial imperfections. [PDF]

open access: yesPLoS ONE, 2018
With the exploitation of offshore oil and gas gradually moving to deep water, higher temperature differences and pressure differences are applied to the pipeline system, making the global buckling of the pipeline more serious.

Creep Buckling of 304 Stainless-Steel Tubes Subjected to External Pressure for Nuclear Power Plant Applications

open access: yesMetals, 2019
The creep-buckling behaviors of cylindrical stainless-steel tubes subjected to radial external pressure load at elevated temperatures—800, 900, and 1000 °C—were experimentally investigated. Prior to the creep-buckling tests, the buckling

Nonlinear Buckling of Fixed Functionally Graded Material Arches Under a Locally Uniformly Distributed Radial Load

open access: yesFrontiers in Materials, 2021
Functionally graded material (FGM) arches may be subjected to a locally radial load and have different material distributions leading to different nonlinear in-plane buckling behavior.

Experimental Investigation and Analysis of Dynamic Buckling of Drill String in Horizontal Well

open access: yesShock and Vibration, 2017
Buckling of tubulars has been the subject of many researches in the past. However, the models in previous research always followed the same assumptions: the friction and rotation effects are ignored.

Pars plana vitrectomy versus scleral buckling for repairing simple rhegmatogenous retinal detachments.

open access: yesCochrane Database of Systematic Reviews, 2019
BACKGROUND Rhegmatogenous retinal detachment (RRD) is a separation of neurosensory retina from the underlying retinal pigment epithelium. It is caused by retinal tears, which let fluid pass from the vitreous cavity to the subretinal space.
