직사각형 Mindlin 평판의 스펙트럴요소모델 개발

초록

This study presents the generic types of spectral element model for the rectangular Mindlin plate using the boundary splitting method and super spectral element method based on the Kantorovich finite strip element method. The proposed spectral element model can be applied to the any plate-like structure subjected to arbitrary boundary conditions, and can be assembled in any plate direction. The accuracy of proposed spectral element model is validated by the exact theory, the finite element method, and the commercial finite element package ANSYS.
