|Title:||Analysis Of Coupled Structural Systems Using Energy Finite Elements And Spectral Elements|
Dos Santos J.M.C.
|Abstract:||The Energy Finite Element Method (EFEM) is based on the approximate solution of partial differential equations resulting from energy balance and joint relationships. The Spectral Element Method (SEM) is an analytical method that uses an approach similar to FE, but, differently from FE methods, SEM represents the exact solution of the wave equation. In this paper, these two methods are used to predict the vibration response of dynamic systems at high frequencies. By using longitudinal and transversal wave energy finite elements for different joint couplings, simulated cases are analyzed, and some important issues related to the sign convention in the joint matrix used in EFEM are discussed.|
