“…The main limitation of such traditional approach is that it requires the extensive and costly experimental programs to characterize the material's properties. An attractive alternative to handle this kind of problem is provided by the framework of micromechanics, which reduces the laboratory expenses, meanwhile helps us throw light on the relations between the material's complicated microstructures and the macroscopic properties of shale rock [9][10][11][12][13][14]. For instances, Hornby et al proposed a theoretical framework to predict the effective elastic properties of shale rocks based on the effective-medium method and found that the anisotropy of shale macroscopic elasticity was attributed to shape, orientation, and connection of the solid and fluid phase [9].…”

“…Further, the constituents of materials can be treated as homogeneous at a certain length scale, but when observed at a smaller length scale, the constituents themselves may become heterogeneous; i.e., the multiscale phenomenon for heterogeneous shale rock materials (cf. Bayuk et al, 2008;Bobko and Ulm, 2008;Bobko et al, 2011;Guo et al, 2013;). For examples, according to Guo et al (2013), the components of shale rocks should contain clays, kerogen, cracks, pores, quartz, calcite and dolomite.…”

“…Bayuk et al, 2008;Bobko and Ulm, 2008;Bobko et al, 2011;Guo et al, 2013;). For examples, according to Guo et al (2013), the components of shale rocks should contain clays, kerogen, cracks, pores, quartz, calcite and dolomite. The material properties are dependent on the microstructural parameters such as the orientation of clay platelets and cracks, pore/crack connectivity and shale mineralogical composition, including quartz, calcite and dolomite (Bayuk et al, 2008).…”

“…Jarvie, (2007) and Li et al (2013) proposed several rock brittleness prediction models by analyzing the differences of mechanical properties of rock with different mineral components. The brittleness indexes were also established by Rickman et al (2008), Guo et al (2013) and Liu et al (2015) based on the Young's modulus (E) and Poisson's ratio (υ). Some other researchers (Altindag, 2010;Tarasov and Potvin, 2013;Xia et al, 2016) evaluated the rock brittleness characteristics from the perspective of the rock failure strength, strain, and energy.…”
