Abstract

The magnetomechanical damping properties of an AISI 403 stainless steel, tested in torsion, were found to behave differently under the action of applied static axial and torsional stresses. A constant torsional stress decreased the damping peak, broadened it, and shifted it to higher stresses. In contrast, a static axial load shifted the peak to lower log decrement values but did not change the peak damping stress. These observations are explained in terms of the effect of the static stresses on the shape of the stress-strain hysteresis loop.
