Title

Research Progress on the Fatigue Behavior of Friction Stir Welded Joints

Abstract

The fatigue fracture resistance of FSW joints is one of the very important properties to assess the capability of FSW structure in practical application. The recent advances on the fatigue properties of FSW joints were summarized in detail, which mainly included the test results of S-N curves, the relationship between fatigue crack growth rate da/dN and ΔK, the threshold value of stress intensity factor ΔKth and the fatigue crack growth behavior in corrosion environment. The influences of various factors on the fatigue behavior of FSW joints were analyzed and the existent problems for the fatigue assessment of FSW were proposed and discussed.
