Helical buckling of thin rods: FE modelling

open access: yesMATEC Web of Conferences, 2018
In this paper, we utilize the Finite Element (FE) method to model twisting of long thin rods and capture the bifurcation scenarios leading to heli- cal buckling and various further post-buckling states.

Post-Buckling Behaviour of Steel Structures with Different Types of Imperfections

open access: yesApplied Sciences, 2022
In this paper, the stability of steel members with a complex initial geometrical imperfection pattern are analysed. This issue is extremely important in the case of slender structures, characterised by multiple close critical loads and modal interactions,

Investigation of critical load of structures using modified energy method in nonlinear-geometry solid mechanics problems

open access: yesNonlinear Engineering, 2022
Geometrically nonlinear analysis is required for resolving issues such as loading causes failure and structure buckling analysis. Although numerical methods are recommended for estimating the exact solution, they lack the necessary convergence in the ...

Similarity consideration of structural bifurcation buckling [PDF]

open access: yesForschung im Ingenieurwesen, 1999
Many structural bifurcation buckling problems exhibit a scaling or power law property. Dimensional analysis is used to analyze the general scaling property. The concept of a new dimensionless number, the response number-Rn, suggested by the present author for the dynamic plastic response and failure of beams, plates and so on, subjected to large ...
