The Finite Element Method FEM , although widely used as an approximate solution method, has some limitations when applied in dynamic analysis. As the loads excite the high frequency and modes, the method may lose precision and accuracy. To improve the representation of these highfrequency modes, we can use the Generalized Finite Element Method GFEM to enrich the approach space with appropriate functions according to the problem under study. However, there are still some aspects that limit thedoi:10.1590/1679-78254265 fatcat:kkfh5aupvbd2vosl6uzxgd2nra
