| Abstract: | Based on the trigonometric shear deformation theory for laminated beams, the motion differential equation of symmetric laminated composite plates is deduced. The motion differential equation discretized by a meshless collocation method based on the inverse multiquadric radial basis function is used to predict the free vibration behavior of symmetric laminated composite plates. Natural frequencies are computed for various material parameters, geometry parameters of laminated plates, and compared with some available published results. Through numerical experiments, the high numerical accuracy of trigonometric shear de- formation theory discretized by the inverse multiquadric radial basis function for free vibration analysis of symmetric laminated composite plates are demonstrated. |
| Keywords: | trigonometric shear deformation theory laminated composite plates vibration inverse mul- tiquadric radial basis functions |
