Abstract
The proposed computational model for crack propagation in high-temperature creep in metallic materials under the influence of a hydrogen environment and neutron irradiation is based on the first law of thermodynamics and the balance of the rates of change of energy components for an elementary crack propagation act in a metallic body under long-term static loading, high temperature, hydrogen-containing environments, and neutron irradiation. The application of the model for determining the residual life of bodies with cracks under the mentioned loading conditions in specified operational conditions is demonstrated using an analogy to Griffith’s problem, which represents a two-dimensional problem for thin-walled structural elements.
