Local Buckling of Thin-Walled Column of Square Cross-Section Made of In-Plane Coupled Laminate. [PDF]

, 2016
The non–symmetric, general laminate exhibits different types of coupling between the extension, shearing, bending and twisting. For practical reasons, the in–plane coupled laminate is a particularly interesting.

Mass Optimisation of Variable Angle Tow, Variable Thickness Panels with Static Failure and Buckling Constraints [PDF]

, 2015
By taking advantage of curved fiber paths, Variable Angle Tow (VAT) laminates increase the design space for tailoring the structural behavior of thin-walled aerospace structures.

Load-shortening behavior of an initially curved eccentrically loaded column [PDF]

To explore the feasibility of using buckled columns to provide a soft support system for simulating a free-free boundary condition in dynamic testing, the nonlinear load-shortening behavior of initially imperfect, eccentrically loaded slender columns is ...

Mode Interaction in Wide Plate with Angle Section Longitudinal Stiffeners Under Compression

Engineering Transactions, 1989
Interaction of nearly simultaneous buckling modes in the presence of imperfections is studied. The investigation is concerned with infinitely wide plate with thin-walled angle longitudinal stiffeners under uniform compression.

Buckling and post-buckling of prestressed stainless steel stayed columns

Engineering Structures and Technologies, 2017
Prestressed stayed compression members are frequently required as very slender load-bearing structural components by both investors and architects. Behavior of these members depends on their geometrical and material properties, prestressing and boundary ...

Hilltop buckling as the A and O in sensitivity analysis of the initial postbuckling behavior of elastic structures

Journal of Civil Engineering and Management, 2009
The coincidence of a bifurcation point with a snap‐through point is called hilltop buckling. In this paper, it either serves as the starting point ‐ the ?

Advances in Stability of Composite Airframe Structures Regarding Collapse, Robust Design and Dynamic Loading [PDF]

, 2008
European aircraft industry demands for reduced development and operating costs, by 20% and 50% in the short and long term, respectively. Structural weight reduction by exploitation of structural reserves in composite aerospace structures contributes to ...

An Investigation on the Nonlinear Free Vibration Analysis of Beams with Simply Supported Boundary Conditions Using Four Engineering Theories

Journal of Applied Mathematics, 2011
The objective of this study is to present a brief survey on the geometrically nonlinear free vibrations of the Bernoulli-Euler, the Rayleigh, shear, and the Timoshenko beams with simple end conditions using the Homotopy Analysis Method (HAM). Expressions
