TLDR
In this article, the authors investigated the influence of variation in material property parameters and plate geometry variables on the natural frequency of FRP sandwich plate panels and obtained closed-form solutions using Reddy's first-and higher-order shear deformation theories.Abstract:
The fibre reinforced plastic (FRP) composite materials configured as sandwich panels are finding increased usage in a variety of structural applications. An important facet in correct usage is an understanding of the dynamic behaviour of such structural configurations. This paper addresses the issue of natural frequencies of sandwich plate panels. The closed-form solutions are obtained using Reddy's first- and higher-order shear deformation theories. The approaches are validated against results from a standard, commercially available finite element analysis package. The paper concludes with a detailed investigation of the influence of variation in material property parameters and plate geometry variables on the natural frequency.read more

A Simple Higher-Order Theory for Laminated Composite Plates
TL;DR: In this paper, a higher-order shear deformation theory of laminated composite plates is developed, which accounts for parabolic distribution of the transverse shear strains through the thickness of the plate.

Elastic wave propagation in heterogeneous plates
TL;DR: In this paper, a two-dimensional linear theory of motions of heterogeneous plates is deduced from the three-dimensional theory of elasticity, which is specialized to cases of symmetrically laminated aeolotropic, orthotropic and isotropic plates.

TL;DR: In this paper, a higher-order shear deformation theory of plates accounting for the von Karman strain was presented, which contains the same dependent unknowns as in the Hencky-Mindlin type first-order deformation theories and accounts for parabolic distribution of the transverse shear strains through the thickness of the plate.
