FATIGUE STRENGTH OF TUBULAR K-JOINTS

In this report the fatigue strength of tubular K-joints is expressed in terms of a ratio of the fatigue strength to the static strength, with which S-N diagrams are established for all the joints tested by the authors. The results show that one S-N curve is a good approximation to represent the fatigue behavior of various types of tubular K-joints supporting the foregoing statement. Since the patterns of of static and fatigue failures vary with the joint types, care must be taken of the limitations within which each S-N curve is applicable. These limitations are also discussed. The S-N diagrams proposed here may be used tentatively as a basis for the design of tubular K-joints.
