摘要：

On the basis of the energy approach, we develop a computational model for the evaluation of the period of subcritical growth of corrosion-fatigue short cracks in elastoplastic plates under the action of long-term cyclic loads and corrosive media in terms of the specific energy components. The results are compared with the available literature data.
