“…The results showed that their compressive strength and elastic modulus are larger than other cellular cementitious materials in the same density range, and the micro-fracture mechanism extremely depends on the microsphere density and the aging of material. Fu et al 10 studied the effects of echelon cracks on the cracking process of gypsum samples subjected to uniaxial compression. Fu et al 11 experimentally studied the failure mechanism of concrete materials with cubic pre-cracks.…”

“…Wang et al 15 studied the coalescence mechanism of rocks with three non-persistent joints using the particle flow modeling. Fu et al 16,17 studied the ligament failure mechanism of concrete samples subjected to 4-point bending test using particle flow code and analyzed the crack propagation process under different dip angles by acoustic emission and discrete-element simulations. Majdi and Beiki 18 proposed an optimal fuzzy C-means clustering model based on the genetic and particle swarm optimization algorithms to calculate the deformation modulus of rocks.…”

In this work, the color difference phase separation (CDPS) approach is proposed to segment the solid and pore phases. Pore‐scale variables are defined to describe the microstructural characteristics. Novel relations to quickly determine the deformation moduli and thermal conductivity are established. Digital–virtual modeling to investigate the mechanical and thermal properties is addressed. The correlation between pore‐scale variables and the mechanical and thermal properties is investigated. Results show that the calculated shear and Young's moduli decrease and the computed Poisson's ratio increases as porosity increases. The deformation moduli and thermal conductivity increase with increasing pore radius for different types of rocks. Excellent consistencies are found between the digital–virtual and realistic experimental results. The proposed method provides useful tools to fast and accurately determine the deformation moduli and thermal conductivity, which is helpful for the underground space and deep energy resource explorations.
