An Iso Geometric Analysis Approach for the Study of Structural Vibrations

The concept of Isogeometric Analysis recently introduced by Hughes et al. [2005] is herein applied to the study of structural vibrations. In this framework, the favourable behaviour of the method is verified and compared with some classical finite element results. Numerical experiments are shown for structural one-, two- and three-dimensional problems in order to test the performance of this promising technique in the field of the analysis of natural frequencies and modes.
