In this paper, crack propagation and coalescence behaviors in rock specimens containing
pre-existing open flaws under uniaxial compression are investigated using the novel …

Particle flow code (PFC 2D) was adopted to carry out a discrete element modeling (DEM) for
the fracture coalescence behavior of red sandstone specimens containing two unparallel …

A rock mass containing non-persistent joints can only fail if the joints propagate and
coalesce through an intact rock bridge. Shear strength of rock mass containing non …

To understand the fracture mechanism in all kinds of rock engineering, it is important to
investigate the fracture evolution behavior of pre-fissured rock. In this research, we …

The present study evaluates the discrete element method (DEM) as a tool for understanding
the step-path failure mechanism in fractured rock masses. Initially, the study simulates crack …

Strength, deformability and failure behaviors of rock masses are significantly affected by the
widespread natural fissures that are often distributed in overlapped patterns. To investigate …

To better understand the interaction of parallel joints and its effect on the mechanical
behavior of jointed rock mass models, the results of a physical experiment program …

Mechanical behavior of a jointed rock mass with non-persistent joints located adjacent to a
free surface on the wall of an excavation was simulated under without and with support …

In this paper we study the performance of the discrete element method (DEM) and the
extended finite element method (XFEM) modelling the crack initiation, propagation and …

It is important to study the mechanical properties of cracked rock to understand the
engineering behavior of cracked rock mass. Consequently, the influence of the length of pre …
