Stochastic heterogeneous material modeling for granular material. Application to wave propagation in ballasted railway track

Résumé

In this work we consider the description of a granular material as an heterogeneous linear continuum medium and the wave propagation in this continuum medium. The purpose of this modeling is to represent the equivalent stress field obtained in a discrete granular model through a continuum stochastic field of mechanical proprieties. One model was build in a finite element method to identify this continuum stochastic proprieties. We applied this approach in a ballasted railway track. The dynamic equations are solved using a Spectral Element approach using one probabilistic model.
