“…Here we present expressions for the transverse shear stiffness and discuss the geometry structure influence on the shear correction factors. Let us note that after the pioneer work of Timoshenko the shear correction factors and similar correcting factors are widely discussed in the theory of beams, plates and shells, see recent publications for beams and plates and reference therein.…”

Three‐layer laminates with thin soft core layer can be found in many engineering applications. Examples include laminated glasses and photovoltaic panels. For such structures high contrast in the mechanical properties of faces and core requires the use of advanced methods to determine effective material properties of the laminate. In this paper we address the application of the first order shear deformation plate theory to the analysis of laminates with thin and soft core layer. In particular, transverse shear stiffness parameters for three‐layered plates with different symmetric configurations are analyzed. For classical sandwiches with thick core layer the result coincides with the Reissner's formula. For the case of thin and compliant core layer the new expression for the effective shear stiffness is derived.

“…Like the linear global (equivalent single-layer) theories, this issue may lead to inaccuracies in determination of the local strain energies and consequently, the resulting stresses [44][45][46][47]. Some researchers have proved the using shear correction factors for higher-order [48] and Di Sciuva zigzag theories [49] enhances the relevant results.…”

A new kind of higher order analysis model is presented for sandwich plates with flexible core, especially ''soft'' core. The governing equations derived from equilibrium differential equations of motions are analytically solved for simply supported sandwich plate with a flexible core. The Navier-type solutions for free vibration analysis and static bending are presented for sinusoidal and uniformly distributed loads. The accuracy and convergence of the present theory and solution are ascertained by comparing with various available results, the author considered vary of length-to-width ratios, Young's modulus ratios between skins and core, thickness ratios between skins and core, and span-to-thickness of sandwich plates. The results show that the present theory can achieve the great accuracy for sandwich plate with flexible core by comparing with existing classical plate theory, first-order shear deformation, higher order shear deformation theory, and finite element software ANSYS.
