Abstract : The multitask objectives of the plan discussed in this proposal are to research the role and effects of fretting on structural life of components; develop and demonstrate the feasibility of integrating candidate fretting fatigue predictive analytic model(s) into structural integrity methods; integrate and implement the techniques for applications to present and future U.S. military weapons programs, commercial aviation, automotive, and mechanical equipment; and provide industry access to the predictive tools and information for commercialization.
