Open AccessProblems 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, ...
Restricted access - publisher's policyThe 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 ...

Restricted access - publisher's policyReal 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 ...
Open AccessThe 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 ...
Open AccessWe 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 ...

Open AccessEm 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 ...

Master thesis (pre-Bologna period)
Open AccessThe 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 ...
