Open AccessA New Simplified Discrete Fracture Model for Shearing of Intersecting Fractures and Faults
Shearing of fractures and faults is important because it can result in permeability change or even induce seismicity—both are keys for efficient and safe energy recovery and storage in Earth systems. Quantitat...
