Abstract
Stress-dependent damping in Cu-Be torsion and flexure suspensions has been measured at stresses up to 1.1 GPa, 95% of the yield stress. The modulus defects of Cu-Be increases from 4.3 X 10(-5) to only 6 X 10(-6 ) in this range. A much larger additional damping, originating at the clamping interface between the suspension and its support, was identif ied and eliminated.
