This project is aimed at advancing theoretical, computational and experimental bases for the fracturing of geomaterials, and providing scientists and engineers with much needed predictive tools for quantitative assessment of the responses. By incorporating previously neglected aspects such as energy minimisation, advanced constitutive modelling, and non-planar interacting fracture growth, confidence in the design and planning of engineering processes in fractured porous media will be increased to the point that costly over/under designs are avoided. Through the use of the tools developed, it will be possible to detect weaknesses in the design, assess the impact and implement effective measures to improve performance.

该项目旨在推进地质材料断裂的理论，计算和实验基础，并为科学家和工程师提供急需的预测工具，用于定量评估响应。通过将以前被忽视的方面，如能量最小化，先进的本构建模，和非平面相互作用的裂缝生长，在断裂多孔介质中的工程过程的设计和规划的信心将增加到一个点，避免昂贵的过度/不足的设计。通过使用开发的工具，将有可能发现设计中的弱点，评估影响，并采取有效措施改善业绩。
