Reduction in strength and stiffness in rocks attributed to an increase in water content has
been extensively researched on a large variety of rock types over the past decades. Due to …

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

Anisotropy is one of the most distinct features that must be considered in rock engineering
whether it is applied in civil, mining, geoenvironmental, or petroleum engineering. Many …

Anisotropy, which is characteristic of metamorphic rocks such as schists, is due to a process
of metamorphic differentiation. Preferred orientation of minerals like mica and chlorite in …

The effect of bedding plane orientations on shear strength and failure mechanisms of shale
is investigated, with an emphasis on the shear parameters of the bedding planes. This study …

Insight into the anisotropic fracture properties of shale under a high in situ stress is important
for the design and optimization of hydraulic fracturing treatment for deep shale formations. In …

Bedding planes or layers can have a serious effect on the mechanical behaviour of shale
rock. Fractures occurring along bedding planes form a fracture network in shale hydraulic …

At present, shale gas plays a significant role in hydrocarbon reservoirs. Hydraulic fracturing
is generally employed in the exploration and exploitation of shale gas. Economic and …

Planes of weakness like schistosity and foliation affect the strength and deformational
behaviors of rocks. In this paper, an attempt has been made to study the elastic and strength …

In this paper, the strength and deformation behavior of transversely isotropic composite rock-
like material, which consists of a hard rock-like material and a weak rock-like material, are …
