Shyriaieva // Nonlinear Dynamics–2010 = Нелинейная динамика–2010 : proceedings the 3rd International Conference, dedicated to the 125th Anniversary of the National Technical University "Kharkov Polytechnic Institute", September 21-24, 2010 / National Technical University "Kharkov Polytechnic Institute" [et al.]. – Kharkov : NTU "KhPI", 2010. – P. 272-277.https://repository.kpi.kharkov.ua/handle/KhPI-Press/41290The method of a durability estimation of rotating turbomachinery blades at forced flexural-flexural-torsional vibrations is offered. The method is based on the methods of Continuous Damage Mechanics and the accurate strain analysis of the pre-twisted blades at the nonlinear vibrations with moderate displacements. The method to solve the strain analysis problem and turbomachinery blades high-cycle fatigue damage estimation as a result of nonlinear vibrations is presented.enThesis
