Mathematical modelling of the formation process of the durable hull of deep-submergance vehicles made from glass-metal composite

The article deals with the technological bases of the production of a structural material with high strength, which is the glass-metal composite manufactured by way of layer-by-layer connection of metal and glass by centrifuge method. It offers a mathematical model of forming a three layer cylindrical hull made from glass-metal composite. Within the framework of the model, the problem has been solved in determining temperature and time behaviour of cooling off and residual stresses. It has been established that, on the edges of interface layers, the residual stresses are much less that the bursting ones, which provides a sufficient margin of safety for the material to be applied in manufacturing deep-submergance vehicles and in space technology.

Key words: mathematical model, glass-metal composite, cylindrical shells, durable hull, deep-water vehicle.
