摘要: An apparatus has been constructed for the study of deformation under tension single and polycrystalline ice. Deformations down to 10−5 cm could be measured. Deformation polycrystals was investigated as a function time, stress, temperature. Whereas strain rate ice decreases with that glacier increases linearly time. The fine‐grained consists an instantaneous elastic deformation, transient creep steady state creep. curves can represented by empirical equations. recovery on removal loads have also plastic flow deduced from residual after complete recovery. This found Newtonian within range stresses viscosity coefficients exponential relationship follows: η1 = 7.5·e+16100/RT poises, where 16 100 calories is energy activatio...
