Microscopic Investigation on Mechanical Response of Wet Granular Materials

Abstract

We numerically investigate the rheological property of wet granular materials. We show that wet granular materials behave like solids even below the jamming point of dry grains. For the pressure, the extended theory of dry granular materials and the simulation are in good agreement. On the other hand, it is confirmed that the behavior of the pair correlation distribution function was different between the dry and wet granular materials.
