Experiments and analysis have shown that the ductile compressive yield stress (at −10°C at 4 × 10 −5 s −1 ) of S2 saline ice, an orthotropic material whose crystallographic c axes are randomly oriented in the plane perpendicular to the long axis of the columnar grains [ Michel , 1978], loaded triaxially both across and along the columnar‐shaped grains obeys Hill's [1950] criterion under low to intermediate levels of confinement. Correspondingly, the ratio of inelastic strains can be described by the attendant associated flow rule.
