  • Coupling of numerical and statistical methods in acoustics 

    Díaz Cereceda, Cristina (Universitat Politècnica de Catalunya, 2010-01-10)
    Master thesis
    Open Access
    Problems in the field of vibroacoustics can be modelled in two fundamental ways. On the one hand, they can be addressed in a deterministic way, using numerical methods like the Finite Element Method. On the other hand, ...
  • Development of a hybrid FE-SEA-experimental model 

    Clot Razquin, Arnau; Meggitt, J.W.R.; Langley, Rob; Elliott, A; moorhouse, A (2019-12-01)
    Article
    Restricted access - publisher's policy
    The vibro-acoustic response of complex structures with uncertain properties is a problem of great concern for modern industries. In recent years, much research has been devoted to the prediction of this response in the ...
  • Sub-structuring of mechanical systems based on the path concept 

    Magrans Fontrodona, Francesc Xavier; Poblet-Puig, Jordi; Rodríguez Ferran, Antonio (Deutsche Gesellschaft für Akustik e.V. (DEGA), 2016)
    Conference report
    Restricted access - publisher's policy
    Real mechanical systems are usually complex. Their modelling with discretisation techniques involve a large number of degrees of freedom/unknowns. This leads to high computational costs especially at high frequencies. An ...
  • The finite strip method for acoustic and vibroacoustic problems 

    Poblet-Puig, Jordi; Rodríguez Ferran, Antonio (2011-12)
    Article
    Open Access
    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 ...
  • The solution of linear mechanical systems in terms of path superposition 

    Magrans Fontrodona, Francesc Xavier; Poblet-Puig, Jordi; Rodríguez Ferran, Antonio (2017-02)
    Article
    Open Access
    We prove that the solution of any linear mechanical system can be expressed as a linear combination of signal transmission paths. This is done in the framework of the Global Transfer Direct Transfer (GTDT) formulation for ...
  • Uma abordagem com superposição modal para problemas de interação fluido‐estrutura 

    Ribeiro, P.M.V.; Pedroso, L.J. (Universitat Politècnica de Catalunya. CIMNE, 2016)
    Article
    Open Access
    Em muitas aplicações práticas da engenharia verifica‐se a interação de domínios distintos, onde os efeitos de acoplamento são importantes na avaliação da resposta estrutural. Um caso de interesse é dado pela interação ...
  • Vibroacoustic modelling of orthotropic plates 

    Villar Venini, Jordi (Universitat Politècnica de Catalunya / Politecnico di Milano, 2011)
    Master thesis (pre-Bologna period)
    Open Access
    The main objective of the work here presented is to extend the calculation of the radiation efficiency to plates whose characteristics differ form the simply supported isotropic rectangular plates. In this work the radiation ...
