A basic study on buckling evaluation method for plate structures
Nihon Kikai Gakkai ronbunshu, 2017 In this paper, we have proposed a simple buckling evaluation method for plate structures of which original shapes and boundary conditions do not change before buckling, and buckling modes of the plates are uniform along longitudinal directions of the ...

Nonlinear buckling analysis of tower crane structure based on movable boundaries
Advances in Mechanical Engineering, 2022 The tower crane is a typical soaring and complex frame structure, and buckling is an important factor affecting its safety and carrying capacity. Considering the special characteristics of the boundary conditions for the boom structure, a numerical ...

Using Symbolic Computation in Buckling Analysis
Journal of Symbolic Computation, 1985 Asymptotic buckling analysis of elastic structures can be considered a well established procedure. It consists in bifurcation analysis of a system of one-parameter differential equations: balance, compatibility and constitutive equations. The aim of this work was to experiment with the use of automatic symbolic computation in the asymptotic bifurcation

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.

Buckling Analysis of Corroded Pipelines under Combined Axial Force and External Pressure
Metals, 2022 Affected by a complex environment, corrosion is a common defect in steel pipelines. Moreover, steel pipelines are subjected to large axial forces during their installation and operation. Corroded deep-sea steel pipelines are prone to local buckling under

Advanced Engineering Materials, EarlyView.CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.
