Summary: Understanding of inelastic behavior of brittle materials (like rocks) under compression requires studies of the underlying microscale deformation mechanisms. Microscopic observations indicate the existence of several distinct micromechanisms. Although their relative importance is unclear, a frictional sliding defect giving rise to tensile microcracking represents one major micromechanism in the brittle-elastic range. It has been studied quantitatively by a number of authors. We briefly discuss several of the proposed models.
