WebFactors determining Poisson’s ratio John J. Zhang and Laurence R. Bentley ABSTRACT Poisson’s ratio is determined by two independent factors, i.e., the solid rock and dry or wet cracks. The former is influenced by the constituent mineral composition. The higher Poisson’s ratio of the rock solid is, the higher is Poisson’s ratio of the rock.
