The prediction of fracturing behaviour in geomaterials (i.e. rock, soil and concrete) under dynamic/impact loads is essential in dealing with a wide range of engineering problems including excavation and mining, blasting and fragmentation, earthquake engineering, impact cratering, and protective structure design However, current knowledge and modelling capabilities of these applications remains empirically based. This project aims to investigate fundamental issues governing the dynamic fracturing of geomaterials and apply this knowledge to advance the understanding and modelling capacity of dynamic fractures in geomaterials.

预测动态/冲击载荷下岩土材料（即岩石、土壤和混凝土）的破裂行为对于处理各种工程问题至关重要，包括挖掘和采矿、爆破和破碎、地震工程、冲击坑和防护结构设计。然而，这些应用的当前知识和建模能力仍然基于经验。该项目旨在研究控制岩土材料动态破裂的基本问题，并应用这些知识来提高对岩土材料动态裂缝的理解和建模能力。
