Elastic and elasto-plastic buckling analysis of perforated steel plates

Vetor, 2013
Many steel structures such as ships and offshore structures are composed by welded stiffened or unstiffened plate elements. Cutouts are often provided in these plate elements for inspection, maintenance, and service purposes, and the size of these holes ...

The Post-Buckling Behaviour of Thin-Walled Columns in the Elasto-Plastic Range

Engineering Transactions, 1986
The post-buckling behaviour in the elasto-plastic range of thin-walled, steel columns subject to uniform compression is analysed. The problem is solved using the Rayleigh-Ritz variational method involving plasticity.

Influence of flanged-cutout on the buckling behaviors of square plate under uniaxial compression

AIP Advances, 2023
Cutouts are commonly found in aerospace, ships, and marine structures, which have a great influence on mechanical properties such as stress concentration, natural frequency, and structural load-bearing performance of the structure.

Local Buckling Behavior of Buckling-Restrained Braces with Longitudinally Profiled Steel Core

Crystals, 2021
One of the most important requirements for a well-designed buckling restrained brace (BRB) under severe earthquake loading is to ensure its stability until the brace achieves sufficient elasto-plastic deformation.

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

Metals, 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.

The buckling strength of a steel containment vessel with discontinuous stiffening rings of a nuclear power plant

Nihon Kikai Gakkai ronbunshu, 2020
A steel containment vessel of PWR (Pressurized Water Reactor) has a circular cylindrical body and a hemispherical head. Since the containment vessel is a thin-walled shell structure, shear and bending buckling might occur in the cylindrical part under ...
