  1. 1.

    Expressions have been derived describing the relationship between the creep rate of a porous material in uniaxial tension (compression) and that of its solid phase.

  2. 2.

    It is shown that the creep rate of a porous solid sharply rises with decrease in its relative density. The rise is the more pronounced the higher the value of the exponent n in the power relationship έ ∼ σn.
