Creep of Ice under Low Stress

Abstract

Uniaxial compressive creep tests on fine-grained polycrystalline ice indicate that secondary strain-rate is proportional to σ^1.8, where σ is applied stress, for the range 0.1 < σ < 0.5 kgf/cm² (10 < σ < 50 kN/m²). On the basis of the present tests, earlier results suggesting linear viscous behaviour at low stress are believed to be invalid.
