Hydraulic fracturing model of a layered rock mass based on peridynamics

Engineering Fracture Mechanics, 2021
Abstract In this work, we proposed a hydraulic fracturing model for layered rock based on peridynamics and studied the mechanism of hydraulic fracturing in a layered rock mass, i.e., complex propagation behaviors at the interface such as crossing, kinking, bifurcation, and arrest.

On Stress Distribution in Layered Rock Masses

Izvestiya, Physics of the Solid Earth, 2018
Spatial distribution of principal stresses in a layered elastic medium is considered in the paper. Transformations of the principal stresses across an interface between the layers are analyzed. A method for reconstructing the spatial stress distributions in layered medium from several spot measurements is proposed. The introduced approach is capable of

Modelling the deformation of underground excavations in layered rock masses

International Journal of Rock Mechanics and Mining Sciences, 1997
Abstract Two small-scale models simulating an opening in a flat-lying layered rock mass were manufactured in the laboratory using ilmenite sand and gypsum mixtures and tested on a loading frame until failure. It was observed that the failure of the opening was initiated by tensile cracking at the mid-section of the immediate roof layer.
