Prediction and prevention of wear

Wear is a life-limiting materials degradation mechanism in many applications. For example, wear by grid-to-rod fretting (GTRF) is the most common cause of fuel leaks in current nuclear reactors. We are developing microscale simulations for modeling wear at the level of single asperities and debris particles. These simulations will lead to better predictions of wear and to the design of materials with improved wear resistance.
