Abstract: AbstractDeep geothermal energy is typically stored in granite reservoirs, and natural granite is highly heterogeneous because it is composed of different sizes and shapes of mineral grains. The mechanical properties of granite are significantly affected… read more here.

Abstract: Abstract In this study, a new calibration procedure was proposed to calibrate the micro-parameters for the flat-joint model. Both uniaxial compression and Brazilian test simulations were conducted on standard and same-porosity specimens using flat-joint model.… read more here.

Abstract: The flat-joint model, which constructs round particles as polygons, can suppress rotation after breakage between particles and simulate more larger compression and tension ratios than the linear parallel-bond model. The flat-joint contact model was chosen… read more here.
