Application of Pseudospectral Method to the Dynamic Analysis of Rectangular Reissner-Mindlin Plate

Pseudospectral 해석법을 이용한 직사각 Reissner-Mindlin 평판의 동적 해석

  • Published : 2000.06.01


A dynamic analysis of rectangular Reissner-Mindlin plate was carried out using pseudospectral method. The pseudospectral method is superior to the finite element method because of more rapid conver gence speed of approximate solutions. Especially, the improvement in accuracy of the pseudospectral method is remarkable. Numerical examples demonstrate the excellent performance and robustness of the pseudospectral method with respect to thickness ratio of rectangular Reissner-Mindlin plate. The natural frequencies of rectangular Reissner-Mindlin plate calculated with the pseudospectral method are more reliable than those calculated with other numerical methods.
