An Efficient Beam Element Based on Quasi-3D Theory for Static Bending Analysis of Functionally Graded Beams [PDF]
Materials, 2019 In this paper, a 2-node beam element is developed based on Quasi-3D beam theory and mixed formulation for static bending of functionally graded (FG) beams. The transverse shear strains and stresses of the proposed beam element are parabolic distributions through the thickness of the beam and the transverse shear stresses on the top and bottom surfaces ...

A quasi-3D theory for vibration and buckling of functionally graded sandwich beams [PDF]
Composite Structures, 2015 This paper presents a finite element model for free vibration and buckling analyses of functionally graded (FG) sandwich beams by using a quasi-3D theory in which both shear deformation and thickness stretching effects are included. Sandwich beams with FG skins-homogeneous core and homogeneous skins-FG core are considered.

An analytical solution for buckling and vibration analysis of functionally graded sandwich beams using a quasi-3D shear deformation theory [PDF]
Composite Structures, 2016 This paper presents a Ritz-type analytical solution for buckling and free vibration analysis of functionally graded (FG) sandwich beams with various boundary conditions using a quasi-3D beam theory. It accounts a hyperbolic distribution of both axial and transverse displacements. Equations of motion are derived from Lagrange’s equations.

Free Vibration of Axially Loaded Composite Beams using a Quasi-3D Theory
Civil-Comp Proceedings, 2015 This paper deals with free vibration behaviour of axially loaded composite beams with arbitrary lay-ups by using a quasi-3D theory, which accounts for shear and normal deformation effects as well as coupling effects arising from the material anisotropy.
