Buckling analysis with the aska program system
Computer Methods in Applied Mechanics and Engineering, 1978Abstract The theoretical and practical considerations involved in extending the very large, general purpose finite element program system ASKA to include linear buckling mode analysis are presented. The main analysis features and their software implementation are discussed in the context of modular processors and data operands.

Torsional buckling analysis of composite cylinders
41st Structures, Structural Dynamics, and Materials Conference and Exhibit, 2000A buckling analysis of composite cylinders under torsion is performed by using the geometrically nonlinear e nite element analysis. A nine-node assumed strain shell-element model with six degrees of freedom per node is used for the analysis. The buckling load of a composite cylinder is found by searching for a bifurcation point on the geometrically ...

On the non-linear buckling and post-buckling analysis of thin elastic shells
International Journal of Non-Linear Mechanics, 1984The aim of the paper is to determine the critical and post-critical behaviour of elastic structures in the frame of a geometrically nonlinear shell theory with moderate rotations. For the fundamental equilibrium path, critical points and post-critical path, a variational method is used, and the equilibrium equation and boundary conditions are obtained ...

Buckling Analysis of Damaged Beams
The presence of damage on structural systems can affect not only their static and dynamic behaviour of structures but also the buckling and post-buckling responses. The present study investigates, by means of the co-rotational method, the effects of concentrated damage on the post-buckling behaviour of beam-like structures, considering large ...Rosalinda Arcoraci +3 more

PERTURBATION APPROACH TO ELASTIC POST-BUCKLING ANALYSIS
Computers & Structures, 1998Summary: This paper shows that effective and reliable computer codes can be obtained by a suitable finite element implementation of the Koiter's perturbation method. However, careful attention has to be paid to all the implementation details in order to avoid kinematic inconsistencies that can strongly affect the results.

Buckling Analysis of Frames With Imperfections and Uncertain Parameters
Volume 10: Mechanical Systems and Control, Parts A and B, 2009The paper describes a procedure for the reliability analysis of frame structures with respect to the buckling limit state under the assumption that the elastic parameters are uncertain and modeled as random variables. The procedure relies on a Response Surface Method adopting simple ratio of polynomials without cross-terms as performance function. Such

‘Analysis of buckle propagation in marine pipelines’
Journal of Constructional Steel Research, 1985Abstract This paper shows how the analysis of minimum, quasi-static, buckle propagation pressures for subsea pipelines may be exactly formulated in terms of the characteristics of ring collapse. A simple mechanistic approach to ring collapse is described which enables the rational incorporation of the effects of material strain hardening. Theoretical

Buckling Analysis of Reticulated Shells
International Journal of Space Structures, 2000The paper presents a comparatively simple method for assessing the global stability of single- and double-layer reticulated shells, assuming rigid connections between the bars. With knowledge of the rigidities of the reticulated shell, a statically equivalent replacement solid shell is established, the buckling of which is extensively treated in the ...
