Clarifying the evaluation methods and factors influencing shale brittleness is of great
practical significance for fracture mechanism analysis, rock mass stability evaluation …

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 …

For a full understanding of the cracking processes in granite, uniaxial compression tests are
conducted on prismatic specimens with pre-existing flaws, and digital imaging and AE …

Fault zones and fault systems have a key role in the development of the Earth's crust. They
control the mechanics and fluid flow properties of the crust, and the architecture of …

Uniaxial compression tests with combined acousto-optical monitoring techniques are
conducted on flawed granite specimens, with the aim of investigating the fracture-related …

Damage surrounding the core of faults is represented by deformation on a range of scales
from microfracturing of the rock matrix to macroscopic fracture networks. The spatial …

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 …

Abstract Acoustic emissions (AE), compressional (P), shear (S) wave velocities, and
volumetric strain of Etna basalt and Aue granite were measured simultaneously during …

В монографии приведены результаты многолетних исследований закономерностей
деформирования нарушений сплошности массивов горных пород. На основе …

Detailed experimental studies of the development of permeability of crustal rock during
deformation are essential in hel** to understand fault mechanics and constrain larger …
