The Effect of Contact Geometry on Fretting Fatigue


Graham Roberts
Department of Theoretical and Applied Mechanics


Some recent research literature has proposed that the initiation of fatigue cracks under fretting conditions is largely dependent on the local macroscopic stress distribution in the contact area. The work reported herein is an investigation of this theory by using contact pads of different geometries which give rise to different stress distributions.
