Development of mathematical models of dynamics and estimation of fatigue life of turbomachines blades with account of geometric nonlinearity

The article presents the results of study of mathematical models of dynamics of turbomachine blades with account of geometric nonlinearity due to temperature and centrifugal forces. Also the authors give the results of calculation of fatigue life of turbomachine blades on the basis of the developed mathematical models. In addition, the authors offer a set of recommendations to improve the fatigue life of turbomachine blades with the account of rotation and uneven heating.
