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 ...

Behaviour of plate elements based on the first‐order shear deformation theory
Engineering Computations, 1990A study of the behaviour of shear deformable plate finite elements is carried out to determine why and under what conditions these elements lock, or become overly stiff. A new analytical technique is developed to derive the exact form of the shear constraints which are imposed on an element when its side‐to‐thickness ratio is large. The constraints are

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.

On the refined first-order shear deformation plate theory of Kármán type
Applied Mathematics and Mechanics, 2000A large deflection theory for laminated plates is set up taking into account transverse shear rotations. Each shear strain component is assumed to depend on the corresponding shear force only, and the shear correction factors are set equal for both directions.

International Journal for Numerical Methods in Engineering, 1997
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 ...

From authors' summary: A laminated plate is discretized by using a single-field displacement finite element model. The procedure is based on neglecting the derivatives of inplane forces and twisting moments, as well as on the neglecting the mixed derivatives of bending moments with respect to in-plane coordinates.

Piezothermoelastic composite plate analysis using first-order shear deformation theory
Computers & Structures, 1994Abstract The response of composite plates constructed of graphite/epoxy laminae with an attached piezoelectric polyvinylidene fluoride layer subjected to mechanical, thermal and electric field loading is considered for various length-to-depth and aspect ratios.

Remarks on “A simple first-order shear deformation theory for laminated composite plates”
Composite Structures, 2014Regarding Huu-Tai Thai and Dong-Ho Choi: A simple first-order shear deformation theory for laminated composite plates. Composite Structures 106 (2013) 754–763. In the above mentioned paper a first-order shear deformation theory is proposed. Splitting up the transverse deflection w into a bending and a shear contribution (w = wb + ws) allows to reduce
