| Abstract: | A mathematical model based on
the actual state of oceanic ice is established. According to
this model, the constitutive relation is derived and compared with the
experiment of uniaxial anti-pressure strength. The formule for the maximum anti-pressure
strength is derived to describe the relations between
compressive strength and strain rate of oceanic ice, and is verified by
tests.
This formula can be used for related structural analysis. |

| Keywords: | oceanic ice mathematical model constitute relation compressive strength |
