文摘

The use of nonlocal index to predict fretting fatigue life of system is proposed. The Modified Wölher Curve Method was applied with the nonlocal index. Experimental validation were done with a bi-axial MTS. Nonlocal map was draw for titanium alloy. Results showed good predictions for the identification of failure's boundary.
