In the failure of quasi-brittle materials such as rocks, microstuctural damage always
precedes macroscopic fracture and manifests itself in the formation of fracture process zones …

Dynamic impact tests were conducted on rectangular marble specimens with flaws to
investigate the effect of the flaw angles and ligament angles on the rock dynamic …

This paper investigates fracture toughness and subcritical crack growth of marble, lherzolite,
and amphibolite under different environments aiming to better understand the effect of …

Understanding the dynamic cracking behaviors and energy evolution of flawed rocks is
highly relevant to underground rock engineering. In this study, multi-flawed rock specimens …

In underground engineering constructions, fractured rock masses are likely to be subjected
to three-dimensional static stress and dynamic loading simultaneously. In this study, via a …

Heterogeneous rock contains numerous pre-existing three-dimensional (3D) cracks, which
control its mechanical and fracturing properties. Considerable effort has been devoted to …

Dynamic impact tests are performed on prismatic marble specimens containing a single flaw
using a modified split-Hopkinson pressure bar device. The effects of pre-existing flaws with …

Internal fissures in rocks are an important factor that complicate the mechanical response of
rock under external loading. With the development of numerous geotechnical projects …

To deeply understand the failure characteristics of defective rock under actual stress
condition, impact tests were conducted on prismatic granite containing two rectangular holes …

Conjugate flaws widely exist in rock masses and play a significant role in their deformation
and strength properties. Understanding the mechanical behaviors of rock masses containing …
