Propagation and complex morphology of hydraulic fractures in lamellar shales based on finite-discrete element modeling

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
We explore the controls of stress magnitude and orientation relative to bedding on the resulting morphology/topology of hydraulic fractures using a combined finite-discrete element method (FDEM).

A rational method for assessing the occurrence of brittle failure in deep tunnels [PDF]

If not properly predicted and accounted for during the tunnel design process, brittle failure can lead to time, cost and safety issues. To support designers in addressing these dangerous and critical phenomena, this paper presents a suggested design ...

Study on the mechanical properties of stratified rock mass based on 3D printing technology and FDEM algorithm

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
Stratified rock mass widely occurs during the process of engineering construction. The weak regions in engineering mainly include bedding plane and crack network, whose mechanical properties have a significant impact on the stability of geotechnical ...
