On buckling of axially functionally graded beams

Pollack Periodica, 2012
In his study Aydogdu analyzed the vibration and buckling of axially functionally graded simply supported beams. By using pre-defined frequency and buckling loads he determined the Young’s modulus in axial direction as a function of axial coordinate. In this study it is demonstrated that there is error in his calculation; moreover, corrected computation

A Comprehensive Review on Vibration Analysis of Functionally Graded Beams

International Journal of Structural Stability and Dynamics, 2020
Beams and beam structures are structural components commonly used in mechanical, aerospace, nuclear, and civil engineering. To meet the different engineering design limitations such as operational conditions, weight, and vibrational characteristics, these components may be made of various materials such as functionally-graded materials (FGMs ...

Dynamics of Functionally Graded Beams on Viscoelastic Foundation

International Journal of Structural Stability and Dynamics, 2014
In the present contribution, the nonlinear dynamics of beams under axial time-dependent excitation is studied. The beams, which rest on a linear viscoelastic foundation, are assumed as axially graded both in terms of geometrical and material properties.

A sinusoidal beam theory for functionally graded sandwich curved beams

Composite Structures, 2019
Abstract To the best of the authors’ knowledge, there is no research work available on FG sandwich curved beams in the whole variety of literature. Therefore, the analysis presented on static behaviour of FG sandwich curved beams in this study is the main contribution and the novelty of the present study.

Delamination of Multilayered Functionally Graded Beams with Material Nonlinearity

International Journal of Structural Stability and Dynamics, 2018
Delamination fracture in multilayered functionally graded, split cantilever beams is analyzed with account taken of the nonlinear behavior of the material. The fracture is studied analytically in terms of the strain energy release rate. The mechanical behavior of the material is described by a power-law stress–strain relation that is not symmetric for

Analytical Solutions for Large Deflections of Functionally Graded Beams Based on Layer-Graded Beam Model

International Journal of Applied Mechanics, 2018
The objective of this paper is to investigate the large deflection of a slender functionally graded beam under the transverse loading. Firstly, by modeling the functionally graded beam as a layered structure with graded yield strength, a unified yield criterion for a functionally graded metallic beam is established.

Flapwise Vibration of Rotating Functionally Graded Beam

Materials Today: Proceedings, 2017
Abstract Functionally Graded materials have been widely used in engineering applications due to the advantage of smooth and continuous variation in material properties, better fatigue life, less stress concentration, lower thermal stresses and attenuation of stress waves. By intelligently designing material constitutions and gradient distributions of

Differential evolution for optimization of functionally graded beams

Composite Structures, 2015
Abstract Differential evolution optimization is used to find the volume fraction that maximizes the first natural frequency for a functionally graded beam. A formulation using three parameters is used to describe volume fraction. Beams with different ratios of material properties are considered. Two methods are used to compute the natural frequencies,
