Extension of Boley’s method to functionally graded beams [PDF]

Acta Mechanica, 2020
AbstractThe objective of this contribution is the computation of the Airy stress function for functionally graded beam-type structures subjected to transverse and shear loads. For simplification, the material parameters are kept constant in the axial direction and vary only in the thickness direction.

Three Kinds օf Porosity օn Functionally Graded Porous Beams

Journal of Architectural and Engineering Research, 2022
In this paper, the effects of three types of porosity on bending behavior of functionally graded porous (FGP) beams are studied. The finite element procedure is established and based on the simple Timoshenko beam theory.

SIMPLE INCREMENTAL APPROACH FOR ANALYSING OPTIMAL NON-PRISMATIC FUNCTIONALLY GRADED BEAMS

Advances in Civil and Architectural Engineering, 2023
This paper presents a simple incremental approach of analysing the static behaviour of functionally graded tapered beams. This approach involves dividing the non-uniform beam into segments with uniform cross-sections, and using two separate finite ...

Static and vibration analysis of functionally graded beams using refined shear deformation theory [PDF]

, 2013
Static and vibration analysis of functionally graded beams using refined shear deformation theory is presented. The developed theory, which does not require shear correction factor, accounts for shear deformation effect and coupling coming from the ...

Flexural analysis of I-section beams functionally graded materials [PDF]

E3S Web of Conferences, 2023
This paper aims to present the flexural behavior of thin functionally graded (FG) I-beams. The characteristics of metal-ceramic materials are defined using a power-law function dependent on volume fraction.

Free vibration of functionally graded beams and frameworks using the dynamic stiffness method [PDF]

, 2018
The free vibration analysis of functionally graded beams (FGBs) and frameworks containing FGBs is carried out by applying the dynamic stiffness method and deriving the elements of the dynamic stiffness matrix in explicit algebraic form.
