Abstract:
A method facilitates reducing stress in a turbine bucket including a metallic base metal. The method comprises providing a turbine bucket including at least one pocket formed therein, and filling at least one pocket defined in the bucket with a polymer composite having continuous fibers oriented in a resin matrix, such that the fibers have an orientation determined in accordance with a pre-selected frequency tuning of the bucket.
