TL;DR: In this paper, carbon fiber-pEEK laminates, manufactured by laser-assisted ATP (LATP) and autoclave, are compared and it is shown that LATP cooling rates are extremely rapid and suggests full through-thickness melting of the pre-preg tape may not occur.

Abstract: The effects of third-order shear deformation theory (TSDT) displacements and advanced nonlinear varied shear correction coefficient on the free vibration frequency of thick functionally graded material (FGM) plates under environment temperature are studied. The nonlinear coefficient term of TSDT displacements is included to derive the advanced equation of nonlinear varied shear correction coefficient for the thick FGM plates. The determinant of the coefficient matrix in dynamic equilibrium differential equations under free vibration can be represented into fully homogeneous equation and the natural frequency can be found. The parametric effects of nonlinear coefficient term of TSDT, environment temperature and FGM power law index on the natural frequency of thick FGM plates are investigated.

TL;DR: In this article, the authors present solutions for both standard laminates, containing combinations of angle plies (±45°) and cross plies(90° and/or 0°), and angle-ply laminate, containing only ±45° ply orientations; chosen to reflect current industrial design practice.

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.
