Numerical simulation examines how Young's modulus and brittleness index influence fracture morphology, suggesting optimization strategies for hydraulic fracturing.
Key Points
Fracture width reduces and length increases with higher Young's modulus, impacting fracturing effectiveness.
Larger Poisson's ratios lead to more uniform fracture deformation, influencing the geometry of fractures.
Increased brittleness index causes fractures to adopt more elongated shapes during propagation.
Higher horizontal stress differences yield more linear fracture paths, guiding fracture design improvements.
