Initial Geometric Imperfections: A Robust, Closed-Section Cold-Formed Box Profile Application Subject to Local Buckling

International Journal of Applied Mechanics and Engineering, 2021
Initial geometric imperfections are important for simulating local buckling in numerical models. References are found in the technical literature regarding open-section cold formed profiles.

Evaluation of Aging Effects on Skin Wrinkle by Finite Element Method

Journal of Biomechanical Science and Engineering, 2008
The reason why the wrinkle suddenly becomes prominent at a middle age is addressed from biomechanical standpoint. The multistage buckling theory we have derived concludes that the sudden enlargement of wrinkle comes from a switch of the specific buckling

On sixfold coupled buckling of thin-walled composite beams [PDF]

, 2009
A general analytical model based on shear-deformable beam theory has been developed to study the flexural–torsional coupled buckling of thin-walled composite beams with arbitrary lay-ups under axial load.

Mechanism of Mechanical Analysis on Torsional Buckling of U-Shaped Bellows in FLNG Cryogenic Hoses

Journal of Marine Science and Engineering, 2022
Floating liquefied natural gas (FLNG) cryogenic hoses can be employed for the transmission of liquefied natural gas (LNG). Usually, U-shaped metal bellows can be applied as the inner lining of FLNG cryogenic hoses.

Buckling modes in pantographic lattices

Comptes Rendus. Mécanique, 2016
We study buckling patterns in pantographic sheets, regarded as two-dimensional continua consisting of lattices of continuously distributed fibers. The fibers are modeled as beams endowed with elastic resistance to stretching, shearing, bending and twist.

Approximation of the critical buckling factor for composite panels [PDF]

, 2012
This article is concerned with the approximation of the critical buckling factor for thin composite plates. A new method to improve the approximation of this critical factor is applied based on its behavior with respect to lamination parameters and ...

Mode transitions in buckling and post-buckling of stretched-twisted strips

International Journal of Non-Linear Mechanics, 2020
Abstract The complex buckling behavior of one of the simplest structures, an elastic thin strip under combined stretch and twist loading represents a fascinating example for structural stability analysis. For stretched-twisted strips, in contrast to solely stretched strips, not just the computation of the post-buckling process but also the simulation

Vibration and buckling of thin-walled composite I-beams with arbitrary lay-ups under axial loads and end moments [PDF]

, 2013
A finite element model with seven degrees of freedom per node is developed to study vibration and buckling of thin-walled composite I-beams with arbitrary lay-ups under constant axial loads and equal end moments.
