Abstract: The results of cylindrical layered silicate glass based material shell manufacturing process mathematical modeling are presented in the article. Problems of cooling of a composit shell and axisymmetric deformation in the course of its formation are considered. The received results testify the possibility of manufacturing of three-layer cylindrical glass-metalic envelope shells which can be used for creation of strong cases for deep-water technical devices. Limiting values of residual pressure on interface surfaces of metal coverings with a glass layer which it is essential less strength of connected materials of a composit cover are received.

Keywords: cylindrical shell, glass-metalic envelope, namomaterial, temperature problem, heat conductivity, numerical method, deformation problem, analytical method, residual stresses.
