Anisotropic shearing mechanism of Kangding slate: Experimental investigation and numerical analysis
Journal of Rock Mechanics and Geotechnical EngineeringThe shear mechanical behavior is regarded as an essential factor affecting the stability of the surrounding rocks in underground engineering. The shear strength and failure mechanisms of layered rock are significantly affected by the foliation angles ...

Application of a Finite-Discrete Element Method Code for Modelling Rock Spalling in Tunnels: The Case of the Lyon-Turin Base Tunnel [PDF]
Brittle failure, or spalling, occurs around openings excavated in hard rock masses with high in situ stresses. It takes place due to the nucleation and growth of cracks around the excavation boundary, induced by the redistribution of stresses following ...

Modeling and Simulation of Damage In The Brazilian Indirect Tension Test Using The Finite-Discrete Element Method [PDF]
, 2018 The Brazilian indirect tension test is used to investigate possible correlations between progressive damage and associated permeability changes. The test offers ease of replicability with a damage behavior known to lead to fracture openings as a tool for

Combined finite-discrete element modelling of key instabilities which characterise deep-seated landslides from massive rock slope failure [PDF]
The expression “landslide from massive rock slope failure” (MRSF) is used to indicate large-scale landslides characterised by a variety of complex initial failure processes and unpredictable postfailure behaviour.
