A coupled MFS-FEM model for 2-D dynamic soil-structure interaction in the frequency domain
In this paper, the authors present a frequency domain coupled model making use of the Finite Element Method (FEM) and of the Method of Fundamental Solutions (MFS) in order to address soil-structureExpand
On the use of a small-sized acoustic chamber for the analysis of impact sound reduction by floor coverings
The use of new technical solutions to minimize the impact noise generated in dwellings is progressively becoming more frequent and in some countries mandatory due to current regulations. EN ISO 140-8Expand
Iterative coupling between the MFS and Kansa's method for acoustic problems
In the present work, a numerical frequency-domain model based on the joint use of two distinct meshless methods (the Method of Fundamental Solutions and Kansa’s Method) is discussed. In this context,Expand
Influence of the cross-section geometry of a cylindrical solid submerged in an acoustic medium on wave propagation
Abstract This paper studies wave propagation in the vicinity of a cylindrical solid formation submerged in an acoustic medium generated by point blast loads placed outside the inclusion. The full 3DExpand
2.5D BEM modeling of underwater sound scattering in the presence of a slippage interface separating two flat layered regions
Abstract This paper describes the use of a boundary element formulation in the frequency domain to investigate the 2.5D acoustic wave propagation in an underwater configuration with a bottomExpand
SOME OBSERVATIONS ON THE BEHAVIOR OF THE METHOD OF FUNDAMENTAL SOLUTIONS IN 3D ACOUSTIC PROBLEMS
The benchmark problem of room acoustics, consisting on the determination of the three-dimensional (3D) sound field generated by a point source placed within a closed acoustic space is here addressedExpand
Frequency domain analysis of acoustic wave propagation in heterogeneous media considering iterative coupling procedures between the method of fundamental solutions and Kansa's method
TLDR
In this paper, numerical frequency domain models based on the joint use of the method of fundamental solutions and of the radial basis function collocation method (also known as Kansa's method) are discussed. Expand
Efficient numerical models for the prediction of acoustic wave propagation in the vicinity of a wedge coastal region
In this paper, numerical frequency domain formulations are developed to simulate the 2D acoustic wave propagation in the vicinity of an underwater configuration which combines two sub-regions: theExpand
Assessment of a simplified experimental procedure to evaluate impact sound reduction of floor coverings
Abstract The impact noise reduction provided by floor coverings is usually obtained in laboratory, using the methodology described in the standard EN ISO 140-8, which requires the use of standardExpand
EXPERIMENTAL AND NUMERICAL ANALYSIS OF SUSTAINABLE SONIC CRYSTAL BARRIERS BASED ON TIMBER LOGS
The acoustic attenuation properties of sonic crystals have been studied in the last decades in different fields of interest. Matching the so-called band gap, in which very high attenuation isExpand
