.... This contact model provides the macroscopic behavior of a finite-size, linear elastic, and either bonded or frictional interface that may sustain partial damage such that the flat-jointed material can mimic the microstructure of angular, interlocked grains. Partial interface damage with continued moment...

... conditions similar to those around a wellbore perforation in dry sandstone? The answer to this question is yes. We can construct a 2D flat-jointed material to represent Castlegate sandstone. Our synthetic material matches much of the macroscopic response (including the direct-tension and unconfined...

... microstructural components are added (such as voids created by removing disks [2] or joints created by replacing contacts with smooth-joint contacts [3]), then it mimics porous or jointed rock.
