Limit-point buckling analyses using solid, shell and solid-shell elements [PDF]
Journal of Mechanical Science and Technology, 2011 In this paper, the recently-developed solid-shell element SHB8PS is used for the analysis of a representative set of popular limit-point buckling benchmark problems. For this purpose, the element has been implemented in Abaqus/Standard finite element software and the modified Riks method was employed as an efficient path-following strategy.

A proposed set of popular limit-point buckling benchmark problems [PDF]
Structural Engineering and Mechanics, 2011 Developers of new finite elements or nonlinear solution techniques rely on discriminative benchmark tests drawn from the literature to assess the advantages and drawbacks of new formulations. Buckling benchmark tests provide a rigorous evaluation of finite elements applied to thin structures, and a complete and detailed set of reference results would ...

Limit point buckling of a finite beam on a nonlinear foundation
Theoretical and Applied Mechanics Letters, 2014 In this paper, we consider an imperfect finite beam lying on a nonlinear foundation, whose dimensionless stiffness is reduced from 1 to k as the beam deflection increases.

Investigations on the limit-point buckling of curved beams
Multidiszciplináris Tudományok, 2023 Calculating the critical load that could lead to beam failure through buckling is a complex issue. This paper intends to analyze the stability of arches taking into account how the curvature, material properties, load positions and geometry affect the behavior.

Nonlinear Instability Behavior and Buckling of Shallow Arches Under Gradient Thermo-Mechanical Loads
Frontiers in Materials, 2022 This paper investigates the nonlinear behavior and buckling of shallow arches under gradient thermal and mechanical loading. The gradient temperature varies continuously along the thickness of the cross section of the arch but uniformly distributes over ...

Nonlinear Buckling and Post-buckling of Shape Memory Alloy Shallow Arches [PDF]
Journal of Applied and Computational Mechanics, 2020 In this work, the nonlinear buckling and post-buckling behavior of shallow arches made of Shape Memory Alloy (SMA) is investigated. Arches are susceptible to large deflections, due to their slenderness, especially when the external load exceeds the ...

Stability of fixed-fixed shallow arches under arbitrary radial and vertical forces [PDF]
Инженерно-строительный журнал, 2020 In the present paper the planar stability of fixed-fixed shallow circular arches is investigated. The arches are made of linearly elastic, functionally graded material and are subject to a concentrated radial or vertical dead force at an arbitrary ...
