Abstract

Fretting Fatigue is an aggressive combination of wear, corrosion, and fatigue that arises in nominally clamped structural components that undergo an oscillatory or vibratory loading. The fretting fatigue phenomenon describes the formation and growth of cracks at the edge-of-contact that arise in these nominally clamped members. The study of this damage mechanism requires a good understanding of the mechanics associated with the geometry, loads, materials, and surface tribology (friction) of the contact. In this particular work, an experimental testing rig is currently under design and developement for investigation of fretting crack initiation life of an orthotropic material with application to space propulsion systems. Experimental investigation of the fretting problem requires a well-characterized fretting test fixture to accurately monitor these contact parameters in-situ. The following report details the progress in development of a well-characterized high frequency, elevated temperature fretting (or contact fatigue) test setup. Design considerations of modifying a piezoelectric driven fretting device to handle elevated temperature operation are presented.
