WG leaders

• Peter Mora (QUAKES, Australia)

• Yilong Bai (LNM, China)

• Terry Tullis (Brown University, USA)

• Teruo Yamashita (ERI, University of Tokyo, Japan)

Aims

• Development of microscopic numerical simulation models for the elementary physical and chemical processes and study of fault rheological properties and constitutive relations.

• Gain understanding of scaling from microscopic to larger scales.

Functions

Micro-model construction (physical/chemical processes). Study of micro-mechanisms and emergent behaviour, fault zone constitutive laws, damage mechanisms, rupture nucleation, granular mechanics (fault gouge), and the frictional instability.
