A double-peaked noise emission curve is seen for HR, whereas a single peak of smaller amplitude is seen for GR. Some results in literature 17, 18, 19 indicate that the shape of the curves may be more intimately related to the microstructure of the material rather than its residual stress state, although such assertions will be avoided in this case.Some results are removed in response to a notice of local law requirement.
