Micro-macro modelling of collapse problems in geomaterials by strain gradient plasticity

拟议的研究旨在提高我们对岩土材料坍塌的基本理解，岩土材料的坍塌与海洋结构物、采矿作业、隧道、岩屑和基础的失效直接相关。开发的先进数学模型将能够准确预测岩土材料的坍塌，并将建立在可测量的微观信息基础上。研究成果将在一个先进的非线性有限元程序中实现，并将为广泛的岩土结构提供更安全和更具成本效益的设计。

The proposed research aims to improve our fundamental understanding of the collapse of geomaterials, which is directly related to the failure of offshore structures, mining operations, tunnels, cuttings and foundations. The advanced mathematical model developed will be capable of accurately predicting the collapse of geomaterials and will be founded on measurable microscopic information. The fruits of the research will be implemented in an advanced nonlinear finite element program, and will lead to safer and more cost-effective designs for a wide range of geostructures.
