Finite Elements in Analysis and DesignAbstract
Ground-borne vibrations are disturbing to human beings. In order to model and reduce these vibrations, the
calculation of the harmonic Green’s-functions of the soil is highly required since the most effective numerical
solution to predict ground-borne vibration is to couple the finite-element and the boundary-element methods.
In this work, we elaborate a direct space-frequency formulation that is especially suitable of material exhibiting
visco-elastic behavior. Moreover, an original formulation of the Proper Generalized Decomposition (PGD)
reduction technique was undertaken in the frequency-space domain. This new approach highly shortens time
computing costs. It is mainly valuable when a parametric study is concerned. Moreover, the PGD resolution
allows providing an off-line solution, thus, the solution is calculated only once.
