Abstract
Dilatancy and pore collapse in rocks play an important role in petroleum and mining engineering problems. Experiments were conducted on rock samples to study the dilatant behavior. An elasto-plastic constitutive model is proposed to describe the shear-volume coupling accurately. Parameter evaluation is carried out using the laboratory test data and a complex optimization procedure. Model predictions are found to be in good agreement with the experimental data. Further extension of this model to predict pore collapse is currently in progress.
