| Summary: | The type of surface damage that occurs in fretting contact depends on the magnitude of
the surface normal and tangential tractions. In existing fretting models the relative displacement is
assumed to be accommodated mainly microslip in the contact surface. The present paper argues
that adhesion forces and elastic deformation in the contact zone may contribute significantly to the
relative displacement during fretting of metals .A simultaneously applied tangential force and
normal into contact appears a adhesion force. A tangential force whose magnitude is less equal on
greater than the force of limiting friction will not give rise on give rise to a sliding motion.It is
determined the energy loss dissipated per fretting cycle. |
