Residual Stress Applications at Pratt & Whitney

Residual stress measurement & validation is a vital task in component development, production, and sustainment. Accurate residual stress assessment is critical, especially in the aerospace industry, due to the high level of safety standards. Depending on the measurement goal and component geometry, different method should be selected for the most accurate and efficient measurements. In this presentation, component-based residual stress applications will be introduced with various kinds of measurement tools and methods. Associated benefits and challenges from these examples can promote new ideas and approaches for better use of measurement techniques.
