On the analysis of viscoplastic buckling
International Journal of Solids and Structures, 1993Abstract For elastic-viscoplastic structures the classical elastic-plastic bifurcation approach to inelastic buckling is not valid. Only an elastic bifurcation point exists in the elastic-viscoplastic case, and the inelastic buckling behaviour is controlled by a strong sensitivity to small imperfections.

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 ...

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

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 ...

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.

‘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 composite laminates
Composite Structures, 1989Abstract The buckling behavior of composite laminated square plates is analyzed with the aid of the finite-element method in which a modified isoparametric linear shell element is used. The in-plane and bending displacements are used together in the formulation of the finite-element method in the case of asymmetric laminates.

Nonlinear buckling analysis of composite shells
15th Structural Dynamics and Materials Conference, 1974An incremental finite element procedure is presented for nonlinear buckling (collapse) analysis of composite shells undergoing large elastic deformations. The type of element employed is a modified version of Clough-Felippa's quadrilateral shell element. The element is made of any number of rigidly bonded orthotropic layers of different thicknesses and
