“…The highest order displacement model under consideration assumes a cubic in-plane strain field, parabolic transverse shear strain field, and a linear transverse normal strain field. Different types of finite elements which took transverse shear and normal deformation into account were developed, based on a higher order theory for the analysis of laminated composite plates [16]. A 6-node 81-DOF C triangular finite element was developed [17] for geometrically and materially linear elastic analysis of multilayered moderately thick composite plates based on a new kind of kinematics and built from Argyris interpolation for bending, and Ganev interpolation for membrane displacements and transverse shear rotations.…”

Efficient and accurate finite elements are crucial for finite element analysis to provide adequate prediction of the structural behavior. A large amount of laminated plate elements have been developed for finite element analysis of laminated composite plates based on the various lamination theories. A recent and complete review of the laminated finite elements based on the higher-order shear deformation theories, including the global higher-order theories, zig-zag theories and the global-local higher-order theories is presented in this paper. Finally some points on the development of the laminated plate elements are summarized.

“…They concluded that it was necessary to provide more than 140 degrees of freedom in terms of displacement polynomials using Ritz method in order to obtain reasonably accurate results, especially for the stress and moment resultants. Verijenko et al [25], introduced a finite element formulation for the analysis of laminated composite plates based on a higher order theory. Different types of finite elements which take into account transverse shear and normal deformation are developed.…”

In the present work, a modified higher-order shear deformation theory is developed to analyze isotropic and composite plates to obtain the static response as well as dynamic characteristics using Ritz solution technique. The displacement-field equations of Lo's higher order shear deformation theory are modified by representing the total rotation of the normal to the mid-plane by two components, bending and shear rotations. The model is valid for thin and thick plates. The plates are subjected to mechanical loads with different types of boundary conditions. A Mathematica code is developed to analyze different plate problems. The obtained results are compared to the available studies solved by different theories and finite element methods. It is shown that the obtained results are accurate using less number of degrees of freedom.
