This paper presents study of Non Destructive Testing’s for fracture analysis of the steam turbine rotor blade through
mechanical analysis. The evaluation of dynamic characteristics of the blade is done by reviewing the literatures in order to
identify the effective methods for detection of cracks. Turbine Blade attachment grooves and blade roots are highly stressed
areas of steam turbine rotors. Serious failure can be obtained in complete turbo generator set due to an unknown crack in blade
roots or blade attachments. It is strongly essential to extend the calculated life of turbo generator set since there is high demand
of power energy worldwide. In case of highly stressed areas of generator rotors and turbine, the advanced NDT methods comes
in demand due to extended operation cycle of turbine. Where the turbine blade roots as well as the turbine blade attachment
grooves of a turbine rotor are comes in most critical range.
