PROPAGATION OF HIGH-TEMPERATURE CREEP CRACKS IN METALS SUBJECTED TO NEUTRON IRRADIATION (A SURVEY)

摘要

We obtain a new equation for finding the rate of propagation of high-temperature creep cracks with regard for the influence of neutron irradiation. By using this equation, we construct a mathematical model for finding the residual life of a plate weakened by a macrocrack under the conditions of high-temperature creep and neutron irradiation. The application of the model is demonstrated for an analog of the Griffith problem. We establish a good correlation of the obtained analytic results with the available experimental data.
