A method for inspecting a turbine blade of a turbine. The method includes operating the turbine and providing a plurality of ablative material strips on the turbine blade. Each strip is fabricated from a common base material and is configured to ablate after exposure to a corresponding predetermined temperature for a corresponding predetermined time period Ablation of a strip indicates a corresponding amount of creep has occurred in the blade. In addition, the method includes visually inspecting the strips at predetermined intervals to determine whether one or more of the strips is ablated.
