Summary
Micro-mechanical and micro-structural aspects of strength variation in rocks under various loading conditions. Understanding rock failure is of vital interest to researchers and practitioners across a wide range of productive activities, including those of critical importance to the Australian economy such as mining and civil engineering design and contracting.

Understanding rock failure is of vital interest to researchers and practitioners across a wide range of productive activities, including those of critical importance to the Australian economy such as mining and civil engineering design and contracting. The failure of rocks is a complex function of interactions between pre-existing micro-cracks and loading conditions. This project will develop a much-needed understanding of the mechanisms leading to rock failure and damage. The project will explore micro and macro-scale mechanisms under both static and cyclic loading conditions. Laboratory testing and micro-analysis will be combined with discrete element modelling to achieve this end.Read moreRead less
