The boundary element method (BEM) in the context of acoustics or Helmholtz problems is
reviewed in this paper. The basis of the BEM is initially developed for Laplace's equation …

The classical boundary element method (BEM) is widely used to obtain detailed information
on the acoustic performance of large-scale dynamical systems due to the nature of semi …

The solution of frequency dependent linear systems arising from the discretization of vibro‐
acoustic problems requires a significant computational effort in the case of rapidly varying …

Abstract Boundary Element Method frequency sweep analyses in acoustics are usually
accompanied by a vast numerical cost of assembling and solving numerous linear systems …

Sophisticated engineering systems are usually assembled by subcomponents with
significantly different levels of energy dissipation. Therefore, these damping systems often …

For several decades, the coupled boundary element and finite element (BE–FE) approach
has been recognized as a potential tool for modeling sound–structure interaction problems …

This paper presents a numerical approach for the design sensitivity analysis of modal
frequencies of elastic structures submerged in an unbounded heavy fluid domain. Because …

The paper presents an extension of the subspace iteration method for application in systems
with viscoelastic damping elements, which are described by both classical and fractional …

The vibration behavior of thin elastic structures can be noticeably influenced by the
surrounding water, which represents a kind of heavy fluid. Since the feedback of the acoustic …

Two highly accurate and reliable eigen-solution techniques, the new homotopy perturbation
method and the extended argument principle method, are proposed for analysing …
