文摘
- •
A novel CDEM method was used for numerical simulation of hydraulic fracturing.
- •
3D initiation and propagation of cracks were investigated using heterogeneous model.
- •
Material heterogeneity has considerable effect on crack initiation.
- •
Crack propagation is controlled primarily by geostress difference.
