Shear effect on cruciform post-buckling
Engineering Structures, 2013Abstract The elastic post-torsional-buckling behaviour of a simply supported cruciform column has been analysed, and its strength has been approximated by assuming that it fails when it first yields due to the maximum normal stress induced by the axial compression. However, torsional shear stresses are induced in the post-buckling regime.

Post-Buckling Analysis of Guyed Towers
Journal of the Structural Division, 1981The post-buckling behavior of short towers, supported by a single set of guy wires is investigated. Using the principle of stationary potential energy, a set of non-linear algebraic equations are obtained for both fixed and hinged-base towers. The equations are solved numerically for several actual systems.

Examination of Plate Post-Buckling Behavior
Journal of the Engineering Mechanics Division, 1977The main results of a number of previous papers by the writers on plate post-buckling behavior are summarized, and additional results for specific plate problems are presented in the form of simple expressions relating load, deflections, end displacements, and stresses.

Post-Buckling Analysis of Cylindrical Shells
Journal of the Engineering Mechanics Division, 1978A method is presented for the calculation of the critical load and post-buckling displacements of elastic structures, and is demonstrated on circular cylindrical shells. The critical load is found by successive extrapolations of the load with the aid of the tangent stiffness matrix determinant.

Post-Buckling Behavior of Determinate Beams
Journal of the Engineering Mechanics Division, 1974A RIGOROUS AND UNCOMPLICATED THEORY FOR THE LARGE ELASTIC DEFORMATIONS OF BEAMS IS PRESENTED AND THE THEORY IS VERIFIED EXPERIMENTALLY BY INVESTIGATING THE POST-BUCKLING BEHAVIOR OF 1-SECTION AND NARROW RECTANGULAR SECTION BEAMS. THE POSTBUCKLING STRENGTH OF DETERMINATE BEAMS IS FOUND TO BE SMALL UNTIL THE DEFORMATIONS BECOME GROSS.

The dynamics of symmetric post-buckling
International Journal of Mechanical Sciences, 1985Abstract This work examines the relationship between natural frequency and compressive load for a conservative elastic mechanical system characterised by symmetric buckling. Application of some general theory shows that for a perfect system, exhibiting a stable-symmetric point of bifurcation, the initial post-buckling curve of compressive load ...

Inelastic Post‐buckling Analysis of Trusses
Journal of Structural Engineering, 1983Geometric and physical nonlinearities are considered in the investigation of the post‐critical ultimate load conditions of space trusses. The inelastic behavior of struts is accounted for by tracing the complete stress‐strain relationships in the elastoplastic range. The unloading characteristics of struts in the post‐critical elastic‐perfectly plastic

Buckling and Post-buckling of Beams
2017This chapter presents buckling and post-buckling analysis of straight beams under thermal and mechanical loads. The Euler and Timoshenko beam theories are considered and buckling and postbuckling behaviors are discussed. The buckling analysis of beams with piezoelectric layers is presented and the effect of piezo-control on the beam stability is ...
