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.

了解岩石破坏是至关重要的利益，研究人员和从业人员在广泛的生产活动，包括那些至关重要的澳大利亚经济，如采矿和土木工程设计和承包。岩石的破坏是预先存在的微裂纹和加载条件之间的相互作用的复杂函数。该项目将开发一个急需的机制，导致岩石破坏和损坏的理解。该项目将探讨静态和循环载荷条件下的微观和宏观机制。实验室测试和微观分析将与离散元素建模相结合，以实现这一目标。
