Досліджено руйнування сталей підводних трубопроводів, яке відбувається в результаті зародження та подальшого розвитку тріщиноподібних дефектів від концентраторів напружень при впливі агресивних середовищ. Запропоновано підхід до оцінювання поверхневого корозійно-втомного тріщиноутворення, який враховує синергетичну дію циклічних напружень та електрохімічних процесів і є ефективним для інженерного застосування.Посилання
