mathematical model, numerical simulation, complex loading, elasticity theory, deformation, stresses, ice cover.

The mathematical model has been made with the applying of theory of small elastic strains and well-tested numerical method for research of stress-strain state of elastic isotropic plate of finite thickness, under the influence of the dynamic load. The practicability of using this mathematical model to study the bearing capacity of the ice cover was shown.
