The work presents the study of changes in the physical and mechanical properties of sea ice in bending. Strength limit σ_в and deformation module Е_в of ice under bending are conditional mechanical characteristics of sea ice. These characteristics do not reflect the actual stress state of ice destruction at the time. The ratio of the module to the strength limit Е_в/σ_в determines the relative radius of curvature of neutral layer in the place of ice destruction. It is shown that this ratio increases with the increase of ice temperature. Dependencies for determining of Е_в and σ_в of sea ice that generalize the experimental data are obtained.
