The Bauschinger Effect examines how abrasive wear between a pair of metal counterfaces is greater For unidirectional sliding.
It has long been known that the stress-strain properties of materials can depend on the way in which stresses are distributed microscopically within the material. This effect is known as the Bauschinger Effect, named after Johann Bauschinger (1834-18931, a mathematician and professor of engineering mechanics at the Technical University of Munich.
The Bauschinger Effect is frequently observed as a decrease in yield strength of metals when the strain direction is changed. The effect can be explained in terms of dislocation buildup in the material, which leads to strain hardening, and is reduced when the strain direction is reversed due to local reversible movement of dislocations and annihilation of dislocations with opposite signs.
The Bauschinger Effect has consequences for tribology, as has recently been reported in the STLE-affiliated journal, Tribalogy Letters by C.Y. Tang, O.Y. Li and G, W. Wen...
