TL;DR: In this article, the natural frequencies of inplane vibration of polar orthotropic annular plates with parabolically varying thickness have been analyzed using a semianalytical method, where the radial and tangential displacements are expanded in the circumferential direction as a Fourier series and the radial behaviour is modelled by finite elements.

TL;DR: In this paper, the bending response of a sectorial annular plate with variable radial thickness based on Kirchhoff plate theory is studied in a hygrothermal environment, where the boundary conditions at the plate circular edges may be simply-supported or/and clamped.

TL;DR: In this paper, the natural frequency of a thick rectangular sandwich panel composed of orthotropic facesheets and a soft core was studied based on a refined shear deformation model, and the effect of transverse shear modulus on flexural vibration of the panel was investigated.

18 Apr 2005TL;DR: In this paper, the vibration of a sandwich panel with two identical isotropic facesheets and a core of hexagonal cells is studied by applying a variational principle, and an analytical solution in Navier form for natural frequency of simply supported rectangular sandwich panel was obtained and the rotational effect was taken into account.
Abstract: As honeycomb core materials have much lower transverse shear modulus than facesheet and are much thicker than the facesheets, the transverse shear deformation plays a significant role on the vibration of sandwich panels. In this paper, the vibration of a sandwich panel with two identical isotropic facesheets and a core of hexagonal cells are studied by applying a variational principle. A simplified model is used to describe the properties of hexagonal honeycomb core. Both low order and high order shear deformation models are employed for shear deformation of the facesheets and core. An analytical solution in Navier form for natural frequency of simply supported rectangular sandwich panel was obtained and the rotational effect was taken into account.

TL;DR: In this article, the buckling behavior of polar and rectangular orthotropic annular disks subjected to a concentrated tangential load acting on the outer edge was analyzed. But some aspects of their buckling behaviour have not been addressed.
Abstract: Circular and annular disks are one of the most commonly used shapes of components in machinery and hence the behavior of these is of utmost interest. Consequently, we find that circular disks have been analyzed extensively. Yet some aspects of their buckling behavior have not been addressed. The aim of the present work is to analyze polar and rectangular orthotropic annular disks subjected to a concentrated tangential load acting on the outer edge. The effect of variation in dimensions, elastic properties, point of load application and number of layers with different fiber orientations is considered. Non-dimensionalized results are presented in the form of graphs and an attempt is made to analyze the observed behavior.
