TL;DR: In this paper, the authors review issues and developments in the field of structure-environment interaction problems, in which the environment is an elastic body, possibly unbounded, and cover in particular the fields of soil-structure interaction, ground-borne noise and vibration emitted by transportation systems and wave diffraction by obstacles in an elastic medium.

TL;DR: A flux-free method for the computation of strict upper bounds of the energy norm of the error in a Finite Element (FE) computation, based on the resolution of a series of local problems on patches of elements and does not require theresolution of a previous problem of flux equilibration, as happens with other methods.

TL;DR: In this paper, the authors generalize the Soize's model in order to account independently for the anisotropy index and the fluctuation level, which leads to major differences in the wave propagation regimes.

TL;DR: The construction of a probabilistic model of the impedance of a pile foundation on a layered unbounded soil using a nonparametric method that allows for the consideration of data errors as well as model errors is presented.

TL;DR: In this article, the authors present a novel approach that allows to couple a deterministic continuum model with a stochastic continuum model, which is based on a volume coupling and a partition of the energy.
