Transport in Stochastic Goupillaud Media
Michael Oberguggenberger, Martin Schwarz
The paper addresses one-dimensional transport in a Goupillaud medium (a layered medium in which the layer thickness is proportional to the propagation speed), as a prototypical cas…

Deterministic and stochastic damage detection via dynamic response analysis
Michael Oberguggenberger, Martin Schwarz
The paper proposes a method of damage detection in elastic materials, which is based on analyzing the time-dependent (dynamic) response of the material excited by an acoustic signa…

Transport in a stochastic Goupillaud medium
Florian Baumgartner, Michael Oberguggenberger, Martin Schwarz
This paper is part of a project that aims at modelling wave propagation in random media by means of Fourier integral operators. A partial aspect is addressed here, namely explicit…
