Free Asymmetric Transverse Vibration of Parabolically Varying Thickness Polar Orthotropic Annular Plate with Flexible Edge Conditions

Free asymmetric transverse vibration of a polar orthotropic thin annular plate with parabolically varying thickness in radial direction have been computed on the basis of classical plate theory considering both the peripheries of the plate elastically restrained against translation and rotation. The fourth order linear differential equation with variable coefficients governing the motion in the...

Free Vibration Analysis of Orthotropic Rectangular Plate Made of Pyroelectric Material

In this paper, the free vibration analysis of a thin orthotropic plate made of pyroelectric material has been carried out and the frequencies are calculated using the Rayleigh-Ritz method. The initial disturbance has been made by the propagation of simple harmonic waves on the surface of the plate through an arbitrary angle. For the symmetric and antisymmetric modes of plane wave propagation, t...

Free Vibration Analysis of Orthotropic FGM Cylinders by a Mesh-Free Method

In this paper, free vibration analysis of orthotropic functionally graded material (FGM) cylinders was carried out by a Mesh-Free method. In this analysis, moving least squares shape functions are used for approximation of displacement field in the weak form of equilibrium equation. Essential boundary conditions are imposed by transformation method. In this simulation, an axisymmetric model is ...

Identification of Orthotropic Plate Stiffness Using Open Hole Tensile Test

Identification of mechanical parameters is still a challenge on real structures. With the improvement of optical full field measurement techniques, it becomes easier, but in spite of many publications showing the feasibility of such methods, experimental results are still scarce. We present here a first step towards a global approach of mechanical identification for composite materials. The cho...
