Structural Integrity assessments in steam turbine power generation blade materials

Project overview

Fatigue in steam turbine blade materials is a growing issue as we try to extend the latter stages of lifetime at end of life of these assets. In particular a focus on fatigue mitigation approaches such as shot peening, coatings and minor overloads on fatigue mechanisms has been studied in a range of projects
