urn:hdl:2117/27707 The finite strip method for acoustic and vibroacoustic problems Poblet-Puig, Jordi Rodríguez Ferran, Antonio Àrees temàtiques de la UPC::Física::Acústica Àrees temàtiques de la UPC::Matemàtiques i estadística::Anàlisi numèrica Structural dynamics--Mathematical models Vibration--Mathematical models Vibroacoustic finite element finite strip method Vibroacústica The finite strip method, widely employed in structural mechanics, is extended to solve acoustic and vibroacoustic problems. The acoustic part of the formulation, including how to handle the most typical acoustic boundary conditions and the fluid structure interaction, is presented. Several realistic problems where the three-dimensional domain of interest has extrusion symmetry are solved. These examples illustrate the advantages of the method: it has smaller computational costs than the finite element method and consequently the analyzed frequency range can be increased.
