Flapwise Vibration of Rotating Functionally Graded Beam
Materials Today: Proceedings, 2017Abstract 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

Thermal Buckling of Functionally Graded Sandwich Beams
Advanced Materials Research, 2019Thermal buckling of new model of functionally graded (FG) sandwich beams is presented in this study. Material properties and thermal expansion coefficient of FG sheets are assumed to vary continuously along the thickness according to either power-law (P-FGM) or sigmoid function (S-FGM) in terms of the volume fractions of the constituents.

Dynamics of Functionally Graded Beams on Viscoelastic Foundation
International Journal of Structural Stability and Dynamics, 2014In 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.

Functionally graded piezoelectric cantilever beam under load
Archive of Applied Mechanics, 2004In the present paper, the problem of a functionally graded piezoelectric cantilever beam subjected to different loadings is studied. The piezoelectric beam is characterized by continuously graded properties for one elastic parameter and the material density. A pair of stress and induction functions in the form of polynomials is proposed and determined.

Thermoelastic analysis of functionally graded porous beam
Journal of Thermal Stresses, 2018We present a thermoelastic analysis of functionally graded porous beams under in-plane thermal loading which is applied as uniform temperature distribution over the entire beam.

Vibrations of Damaged Functionally Graded Cantilever Beams
AIP Conference Proceedings, 2008The paper discusses closed‐form solutions of the problems of free and forced vibrations of a functionally graded cantilever FGM beam with and without damage. The mode of damage considered in the paper is represented by cracks that are perpendicular to the axis of the beam.

On buckling of axially functionally graded beams
Pollack Periodica, 2012In 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

Functionally graded piezoelectric beam under arbitrary loading
2009 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications (SPAWDA 2009), 2009Analytical solutions for functionally graded beams under arbitrary loading are presented in this paper. The material coefficients vary exponentially along the thickness of the beams. The arbitrary loading is expanded in terms of sinusoidal series. For plane stress problems, the stress function and electric displacement function are assumed to consist ...
