Study on Mesostructure Boundary Modeling and Hydraulic Fracture Propagation for Rock Material Based on the PHF-LSM-MT Method

Natural heterogeneous rock material has complex mesostructure and distribution characteristics. An approach to model inclusions with irregular boundary by using the Perlin noise, and considering features, e. g., specific radius, semi-axial ratio, orientation angle and plane filling rate, is introduced. In order to include the mesostructure characteristics of rock material at integration point, the permeability-based hydraulic fracture level set …
