Influence of graphene platelets on the response of composite plates subjected to a moving load

Y. Kiani

Summary: This study investigates the forced vibration response of a composite laminated plate reinforced with graphene platelets (GPLs), considering the different weight fractions of GPLs in each layer. The elastic properties of the composite media are determined using the Halpin-Tsai approach, and the motion equations of the plate are established using the Ritz method with Chebyshev polynomials as shape functions. The time dependent system of equations is solved using the Newmark time marching scheme. Numerical results show the influence of boundary conditions, GPL weight fraction, and GPL distribution profile on the dynamic response of the plate.

Free vibrations of graphene platelet reinforced composite skew plates resting on point supports

Yaser Kiani et al.

Summary: The vibration behavior of skew plates located on point supports is investigated in this study. The point supports can be located on the edges or within the plate domain. A composite laminated plate reinforced with graphene platelets is used, and the weight fraction of graphene platelets varies in different layers, resulting in a piecewise functionally graded media. The elasticity modulus is estimated using the Halpin-Tsai rule, and the mass density and Poisson's ratio are obtained using the rule of mixtures approach. The total strain and kinetic energies of the skew plate are established using the first-order shear deformation theory of plates. The mass and stiffness matrices are obtained using the Ritz method with Chebychev polynomials as shape functions. The effects of point supports with arbitrary number and locations are considered using the method of Lagrangian multipliers. The developed formulation and solution method provide accurate in-plane and out-of-plane frequencies and mode shapes of the plate. Numerical results demonstrate the effects of the number of composite plate layers, weight fraction of graphene platelets, distribution pattern of graphene platelets, position and number of point supports, plate geometries, and boundary conditions on the frequencies of the skew plate located on point supports.

Wachirawit Songsuwan et al.

Summary: This paper investigates the dynamic behavior of functionally graded sandwich plates under multiple moving loads using the first-order shear deformation theory of plates and Lagrange's equations. The study shows that the dynamic deflection has initial fluctuated growth at low moving load velocities, reaching a peak at the critical velocity before decreasing considerably. Additionally, the gaps or distances between the moving loads also play a significant role in predicting the dynamic deflections of the plates when subjected to multiple moving loads.
