A meshless local radial point collocation method for free vibration analysis of laminated composite plates

In this paper a meshless local radial point collocation method based on multiquadric radial basis function is proposed to analyze the free vibration of laminated composite plates This method approximates the governing equations based on first-order shear deformation theory using the nodes in the support domain of any data center Natural frequencies of the laminated composite plates with various boundary conditions, side-to-thickness ratios and material properties are computed by present method The choice of shape parameter effect of dimensionless sizes of the support domain on accuracy convergence characteristics are studied by several numerical examples The results are compared with available published results which demonstrate the accuracy and efficiency of present method (C) 2010 Elsevier Ltd All rights reserved
