FREE VIBRATION OF MOVING LAMINATED COMPOSITE PLATES WITH AND WITHOUT SKEW ROLLER USING THE ELEMENT-FREE GALERKIN METHOD

In this paper, free vibration of axially moving symmetrically laminated plates subjected to in-plan forces is analyzed using the element-free Galerkin method. This category includes symmetric cross-ply and angle-ply laminates and anisotropic plates. The governing differential equation for a moving plate is numerically solved using the Galerkin method. The shape functions are constructed using the moving least squares (MLS) approximation and the essential boundary conditions are introduced into the formulation through the use of the Lagrange multiplier method and the orthogonal transformation techniques. The effect of skew roller and intermediate supports on the natural frequency of plate are examined.
