The Next Step in Micromechanical Studies of Rock Deformationand Failure: Experiments and Theory for More Complicated Value Problems that Include Stress Gradient Effects

本研究的目的是建立一种损伤模型来模拟印第安纳石灰岩空心圆柱体试验中的裂纹扩展，以及其他复杂的边值问题。损伤模型将通过将微力学模型实现为弹性有限元代码来开发。结果可能最终消除对脆性岩石的经验本构关系的需要，而脆性岩石的微观力学模型已经开发出来。

The objective of this research is to develop a damage model to model the crack growth that occurs in hollow cylinder tests of Indiana limestone, as well as in other complicated boundary value problems. The damage model will be developed by implementing a micromechanical model into an elastic finite element code. The outcome could eventually eliminate the need for empirical constitutive relations in brittle rocks for which micromechanical models have been developed.
