摘要：
On the basis of the established relationship between the durability of the material (of glass specimens) and glass products, we develop an algorithm for the analysis of reliability of piecewise-homogeneous shell glass structures. This algorithm is applied to the evaluation of reliability of a composite circular cylindrical shell operating under atmospheric pressure in a medium with different temperatures in different parts of the shell. ?he surface of the glass structure is split into areas of the same material in quasihomogeneous and simple stressed state. On the surface of the structure, we determine the fields of total principal stresses affecting its reliability. Technological (residual) and working stresses are obtained by using the combination of experimental and theoretical methods. Thermal stresses in the structure are computed by applying numerical and analytic methods. Reliability analysis is performed for five years of operation.
