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 …

Damage tolerance design approach such as the fatigue crack propagation approach
provides a more realistic solution for fatigue problems in concrete to overcome the …

To explore the variation in rock acoustic emission (AE) characteristics with strain rate,
uniaxial compression tests at different loading rates and impact loading tests were …

The rock failure process is associated with acoustic emission (AE). Hence, violent rock
failure processes such as rock burst under different stress paths in laboratory can be studied …

The shear properties of bonded rock-concrete interfaces play a crucial role in the analysis of
engineering structures stability. In this paper, laboratory direct shear tests and acoustic …

This paper presents experimental results on the anisotropy of the fracture toughness,
Brazilian tensile strength, and the fracture process zone (FPZ) in granodiorite samples. The …

To investigate the acoustic emission characteristic of rock under different compressive
loading rates, a numerical approach using the bonded-particle model (BPM) is adopted in …

To accurately evaluate the danger from rock bursts during coal mining, uniaxial compression
tests of composed coal rock at different loading rates were carried out. The effect of the rate …

The loading rate is an essential factor that influences the fracture characteristics and
behavior of rock materials. In the study, a series of mode I fracture tests were performed on …

Cyclic loading of coals impacts permeability due to reversible deformation and irreversible
damage and extension to pre-existing fracture networks. These changes in permeability …
