Temperature stress and elastic strain energy in the ice cover of the lake Baikal
The temperature stress, the temperature of first fracture of the ice cover, and the elastic energy stored in the ice volume by the onset of fracture were estimated in the approximation of elastobrittle behavior of an ice cover portion of characteristic size and temperature. It is shown that a rather close agreement between theoretical and experimental data is possible only through refining the model and taking into account its physical properties.
