| Abstract | ||
| This work presents a modified Fourier-Ritz approach for first time is used to study dynamic transverse response of laminated plates with different boundary conditions based on classical plate\'s theory. The transverse displacement component of the plate is represented by Fourier series which is modified by adding auxiliary functions to cosine series so as to accelerate the convergence of the series and the solution, proposed by (W.L. Li, Journal of Sound and Vibration, 273, 619–635, 2004) is corrected in present work. Different boundary conditions, types of lamination cross and angle ply, material types, range of force frequency and thickness schemes, are investigated flexibly and the results are in good agreement with those obtained by other solution techniques. | ||
