“…The effect of thermomechanical loading effect on the flexural and buckling behaviour of the FG sandwich plate structure investigated using [32][33]. As discussed earlier, the HSDT kinematics is further utilised to model the and sandwich and laminated composite panel to compute the static and the dynamic behaviour by Mantari et al [34]. Further, the free vibration frequencies of the FG sandwich structure evaluated computationally by Hadji et al [35] using a refined classical laminated plate theory including four-variables.…”

The bending responses of nanotube-reinforced curved sandwich shell panel structure are studied under the influence of the thermomechanical loading. Further, the temperature dependent material properties of the sandwich structure are assumed to evaluate the exact responses. In addition, the face sheets of the sandwich construction are modeled using different grading pattern through the panel thickness. The final form of the equilibrium equation of the deflected sandwich structure obtained by minimising the total potential energy functional. Now, the equation is solved computationally via a suitable computer code (MATLAB) using the novel higher-order kinematics including the finite element method. The constancy and the accuracy of the current finite element solutions are verified by solving a different kind of numerical examples as same as the published examples. The effect of parameters associated with structural stiffness and the flexural behaviour of the nanotube-reinforced curved sandwich structural panel are examined together with the unlike temperature distributions (uniform and linear) and discussed the final conclusions in detail.

“…There is another type of higher-order theories which use trigonometric, hyperbolic and exponential functions to represent the shear deformation effects. By using these higher-order theories, although several authors have investigated the static, vibration and buckling behaviour of composite plates ([21]- [26]), the existing literature reveals that studies of flexural analysis of composite beams with arbitrary lay-ups are limited. Although the HOBTs offer a slight improvement in accuracy compared to the FOBT, they are computationally more demanding due to higher-order terms included in the theories.…”

The developed theories, which do not require shear correction factor, account for parabolical variation of shear strains and consequently shear stresses through the depth of the beam. In addition, they have strong similarity with Euler-Bernoulli beam theory in some aspects such as governing equations, boundary conditions, and stress resultant expressions. A two-noded C 1 finite element with six degree-of-freedom per node which accounts for shear deformation effects and all coupling coming from the material anisotropy is developed to solve the problem. Numerical results are performed for symmetric and anti-symmetric cross-ply composite beams under the uniformly distributed load and concentrated load. The effects of fiber angle and lay-ups on the shear deformation parameter and extension-bending-shear-torsion response are investigated.

“…Ahmadian and Zangeneh [4] analysed the dynamic characteristic of the rectangular layered composite plate with the help of super element. The dynamic responses of thick multi-layered composite flat/curved panel and sandwich plate are reported using the new HSDT [5,6] kinematic model. Further, Cugnoni et al [7] computed the experimental modal test of Glass/Polypropylene composite plate and validated by comparing them with numerical results of the thin and the thick layered composite shell panel computed via FSDT as well as the HSDT kinematic models.…”

The natural frequency and the transient responses of Carbon/Epoxy layered composite plate structure have been analysed with the help of two higher-order mid-plane kinematics models in this article. The mathematical formulation of the layered composite structure is further utilised to develop a computer programme in MATLAB-15.0, to evaluate the said responses.The practical relevance of the present higher-order models has been established via comparing the present numerical results computed using suitable MATLAB computer code with the in-house experimental test data. Additionally, the fundamental frequency and the transient responses of the carbon fibre reinforced epoxy composite plate structure are simulated via finite element package (ANSYS) with the help of ANSYS parametric design language (APDL) code. The simulated frequencies are compared with those of the present experimental and MATLAB results. Finally, the significance of the proposed higher-order kinematics has been established via solving a different kind of illustrations to investigate the influence of various geometrical and material parameter on the dynamic responses of layered composite structure and discussed in detail.
