this work presents free vibration analysis of laminated rectangular plates with classical boundary conditions based on the classical plate theory (cpt). the first involves an s-fgm plate with different boundary conditions. then involves a two-layer plate in which an s-fgm layer is coated on a homogeneous substrate with classical boundary conditions, simply called an s-fgm-coated plate; the othe...

This paper deals with a general variational formulation for the determination of natural frequencies and mode shapes of free vibrations of laminated thin plates of trapezoidal shape with an internal line hinge restrained against rotation. The analysis was carried out by using the kinematics corresponding to the classical laminated plate theory (CLPT). The eigenvalue problem is obtained by emplo...

In this article, we present anisotropic conductivity measurements by using two kinds of multimode rectangular cavities. Plate-laminated waveguides are fabricated diffusion bonding etched thin metal plates and their sidewalls have characteristics. The is measured cavities when polarization vertical or horizontal to the lamination direction. Transmission characteristics calculated resonant freque...

Abstract The current study employs the finite element method to compare stress concentration pertaining a graphite / epoxy rectangular laminated composite plate that possess holes in different shapes. hole enables redistributing in-plane stresses, impacts factor (SCF), and focuses maximum near hole. ANSYS program has been designed be employed for parametric studies plates have under uniaxial lo...
