Refined First-Order Shear Deformation Theory Models for Composite Laminates
Journal of Applied Mechanics, 2003In the present work, new mixed variational formulations for a first-order shear deformation laminate theory are proposed. The out-of-plane stresses are considered as primary variables of the problem. In particular, the shear stress profile is represented either by independent piecewise quadratic functions in the thickness or by satisfying the three ...

A method for calculating improved transverse shear stresses in laminated composite plates, which bases on the first-order shear deformation theory is developed. In contrast to many recently established methods, either higher-order lamination theories or layerwise theories, it is easily applicable to finite elements, since only C0-continuity is ...

On a consistent first-order shear-deformation theory for laminated plates
Composites Part B: Engineering, 1997Abstract This paper systematically states the consistent first-order shear-deformation theory for laminated plates recently proposed by Qi and Knight. It assumes that only in an average sense does a straight line originally normal to the midplane remain straight and rotate relative to the normal of the midplane, and in a local sense a slight ...

Vibration analysis of twisted plates using first order shear deformation theory
Journal of Sound and Vibration, 2004Abstract Based on general shell theory and the first order shear deformation theory, an accurate relationship between strains and displacements of a twisted plate is derived by the Green strain tensor. An equation of equilibrium for free vibration is given by the principle of virtual work and the governing equation is solved by using the Rayleigh ...

In piezoelectric materials and at the nano-scale, there is a coupling between electrical polarization and strain gradients fields, which is called flexoelectricity. The effects of this phenomenon seem to be negligible in micro/macro scales.

A simple first-order shear deformation theory for laminated composite plates
Composite Structures, 2013Abstract In this paper, a simple first-order shear deformation theory is presented for laminated composite plates. Unlike the existing first-order shear deformation theory, the present one contains only four unknowns and has strong similarities with the classical plate theory in many aspects such as equations of motion, boundary conditions, and ...

Dynamic Stiffness Formulation for Plates Using First Order Shear Deformation Theory
51st AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference<BR> 18th AIAA/ASME/AHS Adaptive Structures Conference<BR> 12th, 2010The dynamic stiffness method for plates is developed to carry out an exact free vibration analysis by using both classical theory and first order shear deformation theory. Hamiltonian mechanics is used to provide a systematic general procedure for the development of the method.

A novel first-order shear deformation theory for laminated composite plates
Steel and Composite Structures, 2014In the present study, a new simple first-order shear deformation theory is presented for laminated composite plates. Moreover, the number of unknowns of this theory is the least one comparing with the traditional first-order and the other higher-order shear deformation theories.

Enhanced First-Order Shear Deformation Theory for Laminated and Sandwich Plates
Journal of Applied Mechanics, 2005A new first-order shear deformation theory (FSDT) has been developed and verified for laminated plates and sandwich plates. Based on the definition of Reissener–Mindlin’s plate theory, the average transverse shear strains, which are constant through the thickness, are improved to vary through the thickness.
