TL;DR: In this paper, the free vibration of angle-ply laminated plates under clamped boundary conditions was analyzed using radial basis functions and Spline functions, and parametric studies were made to investigate the effect of aspect ratio, length-to-thickness ratio, number of layers, fiber orientation and material properties with respect to the frequency parameter.
Abstract: Abstract Two type of numerical approach namely, Radial Basis Function and Spline approximation, used to analyse the free vibration of anti-symmetric angle-ply laminated plates under clamped boundary conditions. The equations of motion are derived using YNS theory under first order shear deformation. By assuming the solution in separable form, coupled differential equations obtained in term of mid-plane displacement and rotational functions. The coupled differential is then approximated using Spline function and radial basis function to obtain the generalize eigenvalue problem and parametric studies are made to investigate the effect of aspect ratio, length-to-thickness ratio, number of layers, fibre orientation and material properties with respect to the frequency parameter. Some results are compared with the existing literature and other new results are given in tables and graphs.

TL;DR: In this paper, the spline and radial basis functions of base mesh free scheme are applied simultaneously to approximate the displacement and rotational functions of angle-ply composite plates, including shear deformation under clamped-clamped boundary conditions.
Abstract: In this study free vibrations of anti-symmetric angle-ply composite plates including shear deformation under clamped-clamped boundary conditions are presented. Two types of numerical methods are adopted to analyze the problem. The spline and radial basis functions base mesh free scheme are applied simultaneously to approximate the displacement and rotational functions. Comparative studies have been made for analyzing the frequency parameters with respect to the material properties, number of layers, fiber orientations, side-to-thickness ratio and aspect ratio. The results are depicted in terms of tables and graphs.

TL;DR: In this paper, the effects of different parameters on the vibration and harmonic behaviour of cross-ply composite plates with anti-symmetric lamination scheme of layers were discussed and the frequency-amplitude relationships were obtained and presented on frequency response function graph.
Abstract: This work presents vibration and harmonic behaviour of cross-ply composite plates with anti-symmetric lamination scheme of layers. Convergence test and comparison studies for different parameters with respect to number of modes have been carried out using the finite element method. The finite element package ANSYS is used to determine the frequency parameter and resonance amplitude of the plate. The effects of different parameters on the vibration and harmonic behaviour, are discussed. The frequency-amplitude relationships are obtained and presented on frequency response function graph. The clamped, simply supported, free and the combinations of boundary conditions are considered. Effects of damping factor on harmonic response are also investigated.
