| Summary: | 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.
