TO RESEARCH OF MECHANICAL CHARACTERISTICS OF FILMS AND FILM STRUCTURES
The approach of research of mechanical characteristics of the thin compositions having non-uniform structure, defects and damages is stated. Polymeric materials are sensitive to influence of various factors. Changes in mechanical characteristics of polymeric films with white and black substrates under sunlight radiation are considered. The influence of snow cover thickness above the film is taken into account. In this research the experimental and theoretical method is used. Analysis of the results is made and conclusions are drawn.
