Abstract

 In this paper, the effect of geometrical parameters on the fretting fatigue of a half-plane in contact with a at and rounded pad is studied. This is accomplished by calculating and comparing the stress states and stress intensity factors of fretting cracks for a number of pad geometries. The pad geometry is represented by the radius of its rounded corners and the width of its central at part. The distribution of dislocation method is employed to calculate the stress intensity factors of fretting induced cracks of different lengths for different values of geometrical parameters. The results of this study can be insightful for improving the geometrical design of an aero-engine compressor disk, as similar contact and damage are prone to occur in its dovetail region.
