Abstract
Abstract: In many industrial applications, the choice of composite over metallic material structures is due to reducing the weight of a system without compromising its strength and stiffness, which is considered one of the most important design criteria. In this article, an analysis of the dynamic response of a honeycomb plate in the XY plane composed of spectral beam elements in each hexagonal cell is performed. For the numerical implementation, it is used the Spectral Element Method (SEM) is a method that does not need a large number of elements in the mesh. A spectrally formulated can be more accurate and computational low-cost than the conventional FEM, generally used to analysis composite structures. The results are validated with the one obtained by ANSYS.
