Fracture origins and crack growth period have been determined. The analysis has been verified by the data of crack growth direct observations.</p>Low cycle fatigue (LCF)fatigue crack kineticselectron fractographyfinite element crack modelingМалоцикловая усталостькинетика усталостных трещинэлектронная фрактографияконечно-элементное моделирование трещин[1.
