Four types of granite widely exported and used in construction around the world were
subjected to 280 accelerated freeze–thaw test cycles, conducted as stipulated in European …

Information relating to the fracture toughness of geomaterials is critical to our understanding
of tensile fracturing, and in particular in geological and rock engineering projects that are …

An understanding of the influence of temperature on brittle creep in granite is important for
the management and optimization of granitic nuclear waste repositories and geothermal …

The rapid determination and analysis of in-situ stress are crucial for ensuring the stability
and design integrity of underground engineering endeavours. This study introduces an …

Understanding of time-dependent deformation and fracture propagation in rock is essential,
since the knowledge of the long-term integrity of rock is required for many subsurface …

We obtained the complete set of dynamic elastic stiffnesses for a suite of “shales”
representative of unconventional reservoirs from simultaneously measured P-and S-wave …

Optimizing the productivity of nonconventional, low‐permeability “shale” reservoirs requires
detailed knowledge of the mechanical properties of such materials. These rocks' elastic …

We investigated the relation between seismic events and fractures induced by hydraulic
fracturing in laboratory experiments under uniaxial loading conditions using granite and …

A method of velocity anisotropy analysis based on conventional ultrasonic transmission
technique is proposed. Multiple transducers are used both to monitor acoustic emission and …

Understanding the tensile fracturing of rocks under high strain-rate conditions (> 20 s− 1) is
challenging due to experimental constraints. The spalling test has been known as a …
