DOI: 10.1016/j.compgeo.2020.103776
Abstract: Abstract Mechanical properties of crystalline rock are greatly affected by its micro-structures which are characterized as highly-interlocked polygon grains and presence of micro-defects. Due to insufficient consideration of micro-structures in crystalline rock, previous simulations using… read more here.
