Residual Stress Measurement Tools and Methods: Industrial View of Current Gaps and Opportunities

Residual Stress Measurement Tools and Methods: Industrial View of Current Gaps and Opportunities

Residuals stress measurement is necessary in several aspects of product development and sustainment: structural analysis of components with residual stress, process quality validation, model development and validation, and understanding the root-cause of failure events. Especially in the aerospace industry, accurate residual stress assessment is critical due to the higher safety standards. However, limited tools and methods are available for different components and applications. Goal of this presentation is to review pros and cons of the various methods, discuss the technical challenges in stress determination, and introduce potential solutions to overcome the current limits.
