- Аннотация: The relevance of choosing an adequate version of the problem statement onthe influence of corrosion processes on ensuring the safe operation ofmaterials and structural elements is beyond doubt. Problem statement optionsfor the delayed fracture of a rod stretched under creep conditions areconsidered. Two problem statement options are suggested: taking into accountthe multistage propagation of the diffusion–corrosion process throughout theentire thickness of the rod and taking into account the conjugation of thesolutions at the boundary of the corrosion layer. To solve the problem, amechanical-and-mathematical model has been developed, including themodified diffusion equation, the kinetic equation for damage accumulation,and the relation for the chemical interaction parameter. The parameters of thismodel are determined based on the experimental dependence of the corrosionfilm thickness on time. The multistage process of the corrosion layers fractureunder the influence of increasing effective stress is taken into account.
