A technique is developed for fabrication of a shell from glass-metal composite based on the borate glass and aluminum alloy. The metal–glass interface was studied by the optical and atomic force microscopy, it was found the presence of a diffuse layer with thickness of about 1 micron. The diffuse layer composition was studied by the XPS.

The analytical method of residual strains determination on joints of layers of a glass-metal cylindrical shell arising in the course of its cooling description is provided in article. For the numerical implementation of the proposed model modern numerical and digital-analytical methods were used. In connection with the exponential change of the required functions close to butt ends of the shell numerical methods lead to instability of calculation. In order to overcome this obstacle, Godunov’s method of discrete orthogonalization was applied. It has significantly leveled disturbance peaks of strains on the surfaces conjunction of the composite shell layers.
