Fourier representation of geometrical imperfection for probabilistic buckling analysis
Jurnal Ilmiah SINERGIThis research studies the first part of the failure of a compression member structure due to buckling. This unstable equilibrium collapse, exposes brittle failure which occurs suddenly and therefore should be avoided wherever possible.

Modelling Initial Geometric Imperfections of Steel Plane Frames Using Entropy and Eigenmodes
International Journal of Mechanics, 2023 The article introduces an innovative approach to modelling initial geometric imperfections in steel plane frames. Initial imperfections are introduced using the analysis of normalised deformations of elastic buckling modes. The scale of these modes is assessed by applying Shannon entropy and potential energy analysis.

Post-Buckling Range of Plates in Axial Compression with Uncertain Initial Geometric Imperfections [PDF]
Applications of Mathematics, 2002 The paper deals with the worst scenario method which is applied to von Kármán equations with uncertain initial deflection. Assuming two mode initial and total deflection and using Galerkin method, the problem leads to a system of two nonlinear algebraic equations with one or two uncertain parameters.
