摘要：

This work describes research methods of the complex problem solution to estimate strength and durability of rotation shells with an account of plastic deformations, temperature creep, the hydrogen corrosion and degradation of the material properties in time. The practical calculation of the stressed strained state accounts of the single-layer conical shell. During the research, the values of the stresses on the shell surface and the destruction time are defined, with the effects of hydrogen-containing medium both taken into account and not. In addition, in the elastic, elastic-plastic the creep deformation statements have been calculated for this shell with ANSYS tools. The results obtained in this work show that the best approach to the modeling of the shell stress strain state is the use of multiple software products using different material and geometry models and the subsequent joint analysis of the calculation results. Under certain conditions, which are impossible to predict in advance, the shells calculation for strength and durability without the influence of such factors as damage at the creep and at high-temperature hydrogen corrosion may have incorrect results.
