Abstract
In this paper the use of Hierarchical Finite Element Method (HFEM) in free vibration of curved beams is explored. The traditional Finite Element Method has been applied in dynamic structural problems over the years, but when searching for higher vibration frequencies a great computational effort is necessary. In this context, two hierarchical finite element approaches are proposed in order to achieve more accurate results than simple FEM mesh refinement, called h refinement. The proposed HFEM uses the Lobatto and Bardell polynomials to p refinement. The results are compared with references found in literature.
