The Engineered Residual Stress Implementation (ERSI) Working Group

Hill Engineering is presenting an update on the Engineered Residual Stress Implementation (ERSI) Working Group at the upcoming 2017 North American Residual Stress Summit in Dayton, OH. The Residual Stress Summit brings together residual stress users and developers. Hill Engineering’s presentation will include an overview of ongoing work within the Engineered Residual Stress Implementation Working Group related to cold expanded holes, fatigue and fracture analysis, and similar topics. The abstract text is presented below.

The application of engineered residual stresses on new and legacy USAF weapon systems provides an opportunity to significantly extend the fatigue life at critical locations. In order to reach required service life goals and recurring inspection intervals within budgetary constraints, the ability to implement engineered residual stress into analyses is essential. However, it has been repeatedly demonstrated that in order to properly measure, apply, and analyze engineered residual stresses, sophisticated analytical tools and advanced technical knowledge and training are required. The Engineered Residual Stress Implementation working group provides the opportunity for collaborative discussion and development of best practices supporting engineered residual stress implementation. The ultimate goal of the working group is a framework of tools and processes for the general application to aircraft structures, avoiding expensive point design and offering benefits to all stakeholders.
