Limit point buckling of a finite beam on a nonlinear foundation

open access: yesTheoretical 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.

Nonlinear Buckling of Fixed Functionally Graded Material Arches Under a Locally Uniformly Distributed Radial Load

open access: yesFrontiers in Materials, 2021
Functionally graded material (FGM) arches may be subjected to a locally radial load and have different material distributions leading to different nonlinear in-plane buckling behavior.

Nonlinear Instability Behavior and Buckling of Shallow Arches Under Gradient Thermo-Mechanical Loads

open access: yesFrontiers 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]

open access: yesJournal 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]

open access: yesИнженерно-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 ...

Multiple Equilibria and Buckling of Functionally Graded Graphene Nanoplatelet-Reinforced Composite Arches with Pinned-Fixed End

open access: yesCrystals, 2020
This paper presents an analytical study on the multiple equilibria and buckling of pinned-fixed functionally graded graphene nanoplatelet-reinforced composite (FG-GPLRC) arches under central point load. It is assumed that graphene nanoplatelets (GPLs) in

FUNDAMENTAL MODELS OF STRUCTURAL STABILITY

open access: yesRudarsko-geološko-naftni Zbornik, 2017
In this paper, basic structural stability phenomena are described. After some general comments about stability in the field of civil engineering, four elementary sources of nonlinearity are mentioned: of equilibrium equations, strain (geometry) relations,

Influence of geometrical imperfection on critical temperature evaluation for steel corrugated arch sheets exposed to fire [PDF]

open access: yesMATEC Web of Conferences, 2019
The critical temperature for an arched corrugated steel sheet exposed to fully developed fire is determined in this paper. The analysis is performed on 3D numerical model developed within the ANSYS computational environment with parameters calibrated ...
