Wet granular matter under pressure and shear forces — •Beatrix Schulz1 and Michael Schulz2 — 1Institut für Physik, Martin-Luther-Universität Halle-Wittenberg — 2Abteilung für Theoretische Physik, Universität Ulm
Granular matter is a central topic of physical research in complex systems during the last two decades. Although the main stream of investigations is focussed on dry granular materials, the predominant part of real granular matter contains a liquid fraction. The combination of solids, liquids and gas phases leads to several new interactions effects due to the capillar forces. We present a combined numerical and analytical study of wet granular matter under time-dependent pressure and shear forces. Furthermore, we consider in this study reversible and irreversible bridging processes which allow to explain geophysical phenomena observed in wet granular matter.
