This article reviews the effect of weak interfaces on crack propagation in rock and some
other analogous brittle materials from phenomenon to mechanism. In this review, a variety of …

The textural characteristics of rocks influence their petrophysical and mechanical properties.
Such parameters largely control rock mass stability. The ability to evaluate both immediate …

After the excavation of deep underground engineering, the complex 3D high-stress
redistribution occurs in the surrounding rock, resulting in deterioration of mechanical …

This monograph deals with the part of the field of experimental rock deformation that is
dominated by the phenomena of brittle fracture on one scale or another. Thus a distinction …

A grain‐based Universal Distinct Element Code model was developed to generate a
deformable polygonal grain‐like structure to simulate the microstructure of brittle rock. It …

This paper investigates the pattern of crack coalescence and strength of a sandstone-like
material containing two parallel inclined frictional cracks under uniaxial compression, with …

Fractures in the forms of joints and microcracks are commonly found in natural rocks, and
their failure mechanism strongly depends on the crack coalescence pattern between pre …

The influence of rock mineral composition and mineral grain size on basic rock strength
performance and AE characteristics have been studied, 13 different rocks microstructures …

The microstructure of rock is known to influence its strength and deformation characteristics.
This paper presents the results of a laboratory investigation into the effects of grain size on …

The purpose of this paper is to demonstrate the influence porosity and fissuration exert on
the physico-mechanical properties and durability of nine Portuguese ornamental granites …
