Properties benchmark of granular and viscous analogue materials

Organised by Matthias Klinkmuller (University of Bern), Matthias Rosenau (GFZ Potsdam), David Boutelier (GFZ Potsdam), Helga Kemnitz (GFZ Potsdam) and Guido Schreurs (University of Bern).

The material properties are determined by Matthias Rosenau and Matthias Klinkmuller using the facilities at GFZ Potsdam. The properties of sand are determined with the Schulze Ring-Shear Tester (http://www.dietmar-schulze.de/fre.html). The computer-controlled Ring-Shear Tester RST-01.pc serves for determining the frictional properties of granular materials including the angle of internal friction for fault initiation (first peak strength), fault reactivation (second peak strength) and fault sliding (dynamic-stable strength). The Schulze Ring-Shear Tester is certified and the apparatus and measuring procedure is described in a standard available from ASTM international (document nr. ASTM D6773-02; http://www.astm.org). The bulk modulus is measured with a uniaxial compression tester at GFZ Potsdam.

The following parameters are determined:

The viscosity of silicone materials is determined with a Rheometer RC 20.1.

More information is in Klinkmuller et al. (2008, extended abstract to the GeoMod2008 pre-conference workshop) and in the description of the GeoMod2008 experiments.
