Layerwise solution of free vibrations and buckling of laminated composite and sandwich plates with embedded delaminations
(Elsevier Ltd, 2014)
Layerwise plate theory of Reddy, extended for the analysis of delaminations, has served as a basis for development of enriched finite elements. The proposed model assumes layerwise linear variation of in-plane displacements ...
Thermal buckling of laminated composite plates using layerwise displacement model
(Elsevier Ltd, 2016)
In this paper thermal buckling of laminated composite plates, based on Layerwise Theory of Reddy and new version of Layerwise Theory of Reddy, presented for the first time, are formulated using the principle of virtual ...
A finite element model for propagating delamination in laminated composite plates based on the Virtual Crack Closure method
(Elsevier Ltd, 2016)
In the paper, a simple and efficient algorithm to track a moving delamination front of arbitrary shape, using a laminated finite plate element model in conjunction with the Virtual Crack Closure Technique (VCCT), is proposed. ...

Shear deformable dynamic stiffness elements for a free vibration analysis of composite plate assemblies - Part I: Theory
(Elsevier Ltd, 2017)
A procedure for developing the dynamic stiffness matrix of a completely free laminated composite plate based on the first-order (FSDT) and higher-order shear deformation theory (HSDT) is presented. The proposed method ...
Free vibrations of laminated composite shells using the rotation-free plate elements based on Reddy's layerwise discontinuous displacement model
(Elsevier Ltd, 2016)
The goal of this paper is to develop a computational model for the free vibration analysis of laminated composite shells with embedded delaminations. Laminated composite shells of different shape are modeled using the ...
Free vibration analysis of stiffened and cracked laminated composite plate assemblies using shear-deformable dynamic stiffness elements
(Elsevier Ltd, 2017)
In the paper, the dynamic stiffness method based on the HSDT and FSDT plate theories is applied to study free vibration characteristics of composite stiffened and cracked plate assemblies. The dynamic stiffness matrices ...
Shear deformable dynamic stiffness elements for a free vibration analysis of composite plate assemblies - Part II: Numerical examples
(Elsevier Ltd, 2017)
The dynamic stiffness elements based on the HSDT and FSDT (and the corresponding dynamic stiffness matrices of a laminated composite plate) have been implemented into the original MATLAB code, and a variety of numerical ...
