WebHaving various studies on a wide range of experimental data, Hoek and Brown (1980, 1997) stated that the relationship between the maximum and minimum stress at the point of failure can be expressed as: (A-7) where m and s are constants parameters depending on the properties of the rock. The Drucker–Prager yield criterion is a pressure-dependent model for determining whether a material has failed or undergone plastic yielding. The criterion was introduced to deal with the plastic deformation of soils. It and its many variants have been applied to rock, concrete, polymers, foams, and other pressure-dependent materials.
