The solution is done by the finite element method in three-dimensional arrangement using ANSYS PC. Mathematical model of rotor blade has been developed; numerical analysis of its natural frequencies, mode shape, and diagram of relative dynamic stress distribution taking into account thermal fields and centrifugal forces has been carried out, stress localization has been revealed. Practical recommendations for reducing stress intensity level in structure are given. Results can be applied at turbine construction enterprises.
