For complex nonlinear problems of elasto-plastic deformation of the pipe and when structural elements relaxed stress concentrators such as cracks and defects achieved increasing accuracy of the internal forces and the improvement of the basis of the methodology of calculation of strength. The problems are reduced to the solution of boundary integral equations for displacements and energy component on the surface structure, and functions with respect to crack . The analysis of elastic- plastic deformation of tubes improved technology maintenance and repair of pipelines and construction of devices designed for repair work of pipelines in mountainous terrain.5481 Product Description popup.authors Білобран Богдан Степанович Бондарчук Богдан Валентинович Войтович Микола Іванович Гутий Андрій Володимирович Кичма Андрій Олексійович Ковальчук Роман Анатолійович Кузьо Володимир Ігорович Новіцький Юрій Ярославович Носов Юрій Євгенович Палюх Володимир Михайлович Савула Роман Степанович Силованюк Віктор Петрович Стасюк Богдан Мирославович Харченко Євген Валентинович Харченко Лідія Євгенівна Яськов Віктор Васильвич popup.nrat_date 2020-04-02 Close
