Abstract A refined trigonometric shear deformation theory (RTSDT) taking into account transverse shear deformation effects is presented for the thermoelastic bending analysis of functionally graded sandwich plates. Unlike any other theory, the number of unknown functions involved is only four, as against five in case of other shear deformation ...

A refined zigzag nonlinear first-order shear deformation theory of composite laminated plates
Composite Structures, 2008A refined nonlinear zigzag shear deformation theory of composite laminated plates is presented using a modified mixed variational formulation. The theory accounts for continuous piecewise layer-by-layer linear variation approximation in the thickness direction for the displacements.

A C0 plate bending element with refined shear deformation theory for composite structures
Composite Structures, 2006A simple C0 finite element formulation with embedded higher-order shear deformation theory and a 3-dimensional state of stress and strain for thick and thin laminated composite plates has been presented. The assumed displacement model accounts for parabolic variation of transverse shear strains and linear variation of normal strain through the plate ...

Composites Part B: Engineering, 2012
Abstract A refined shear deformation theory for free vibration of functionally graded plates on elastic foundation is developed. The displacement field is chosen based on assumptions that the in-plane and transverse displacements consist of bending and shear components, and the shear components of in-plane displacements give rise to the parabolic ...

Structural Engineering and Mechanics, 2015
This paper presents a nonlocal shear deformation beam theory for bending, buckling, and vibration of functionally graded (FG) nanobeams using the nonlocal differential constitutive relations of Eringen. The developed theory account for higher-order variation of transverse shear strain through the depth of the nanobeam, and satisfy the stress-free ...

A refinement of the transverse shear deformation theory for multilayered orthotropic plates
1983Summary: A refinement transverse shear deformation theory for multilayered orthotropic plates is developed. The displacements are assumed piecewise linear across the thickness and allow the contact conditions for the displacements and the transverse shearing stresses at the interfaces to be satisfied.

A Refinement of Mindlin Plate Theory Using Simultaneous Rotary Inertia and Shear Correction Factors
Journal of Vibration and Acoustics, 2018We revisit Mindlin's theory for flexural dynamics of plates using two correction factors, one for shear and one for rotary inertia. Mindlin himself derived and considered his equations with both correction factors, but never with the two simultaneously. Here, we derive optimal values of both factors by matching the Mindlin frequency–wavenumber branches

Hygrothermal and Imperfection Effects on FG Nanobeam Vibration via a Refined Integral Shear Theory
International Journal of Computational MethodsIn this study, a higher-order approach incorporating a new polynomial-exponential integral shear strain field is established to examine the vibration response of functionally graded (FG) nanobeams subjected to hygrothermal loading and material composition imperfections.
