The energy approach for the material damage and the defects expansion estimating under the operating loads is formulated. For damage degree estimating of structural elements the technique for determining the material mechanical characteristics and the strain distribution in the stress concentrators vicinity is developed.5481 Product Description popup.authors Іваницький Ярослав Лаврентійович Вікович Ігор Андрійович Гембара Оксана Володимирівна Кунта Ольга Євгенівна Палюх Володимир Михайлович Поліщук Леонід Клавдійович Стасюк Богдан Мирославович Харченко Євген Валентинович Чумало Галина Василівна popup.nrat_date 2020-04-02 Close
