Thermal Stresses in Functionally Graded Beams

AIAA Journal, 2002
Thermoelastic equilibrium equations for a functionally graded beam are solved in closed-form to obtain the axial stress distribution. The thermoelastic constants of the beam and the temperature were assumed to vary exponentially through the thickness. The Poisson ratio was held constant.

Vibration Analysis of Functionally Graded Timoshenko Beams

International Journal of Structural Stability and Dynamics, 2018
The vibration behavior of a functionally graded Timoshenko beam is investigated by applying the transformed-section method. The material properties of a functionally graded (FG) beam are assumed to vary across the thickness according to a simple power law. The cross section of FG beam with two constituents is first transformed into an equivalent cross

Analysis of Functionally Graded Beam

INROADS- An International Journal of Jaipur National University, 2018
In this paper, static analysis of FGM (functionally graded material) beam is carried out under the framework of Euler–Bernoulli beam theory. Axial stress distribution has been determined for a simply supported FGM beam made of Aluminium and Zirconia. The material properties of FGM are assumed to vary through the thickness, whereas Poisson ratio is held

Coupled Thermoelasticity of Functionally Graded Beams

Journal of Thermal Stresses, 2008
This paper presents the finite element solution of an Euler–Bernoulli beam with functionally graded material (FGM) subjected to lateral thermal shock loads. The FGM beam is assumed to be graded across the thickness. The material properties across the thickness direction follow the volume fraction of the constitutive materials in power law form.

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

Thermal Buckling of Functionally Graded Sandwich Beams

Advanced Materials Research, 2019
Thermal 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, 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.

Functionally graded piezoelectric cantilever beam under load

Archive of Applied Mechanics, 2004
In 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.
