A numerical toolkit to understand the mechanics of partially saturated granular materials

Modelling and numerical aspects of fluid-saturated granular materials: application to shear flows

Introduction: In the first part of this talk, we present an algorithm for the numerical treatment of twopressure, two velocity continuum models for heterogeneous, immiscible mixtures [1]. This algorithm has been employed in a numerical study of unsteady shear flows of fluid-saturated granular materials, as predicted by the continuum model of [2]. A representative sample of these results are pre...

Mathematics and mechanics of granular materials

from linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar

chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...

hy si cs Seismoelectric wave propagation numerical modelling in partially saturated materials

To better understand and interpret seismoelectric measurements acquired over vadose environments , both the existing theory and the wave propagation modelling programmes, available for saturated materials, should be extended to partial saturation conditions. We propose here an extension of Pride's equations aiming to take into account partially saturated materials, in the case of a water–air mi...

Exploring the micro - mechanics of triaxial instability in granular materials

14 The instability of granular materials due to water infiltration under fully drained conditions has been 15 previously considered in experimental studies. While laboratory experiments can provide macro-scale 16 insight into drained instability, the micro-mechanics under such conditions are yet to be explored. 17 This study has employed the Discrete Element Method (DEM) to simulate constant sh...
