MICROMECHANICAL MODELLING OF FAULT GOUGE DYNMICS: TOWARDS AN IMPROVED FAULT CONSTITUTIVE RELATION
Grant number: DP0772409
The human and economic costs of geological and other particulate media related problems in Australia are staggering. These include geological hazards (e.g. landslides and earthquakes; the Newcastle earthquake cost around $4 billion and 13 lives), to particulate processes prevalent in Australia's major export industries (e.g. coal export valued at $9.3 billion, iron ore at $3.8 billion, and wheat at $3.4 billion), to Australia's 810,000 km granular paved road network that costs around $5.5 million per day to maintain. The program will deliver new knowledge and advanced analytical and predictive modelling tools capable of fuelling breakthroughs in earthquake forecasting res..View full description
