“…The threshold values of table 1 are just above this value. This result is consistent with our previous publication [7] where we found that the threshold case for a much thicker aluminum sample closely corresponded to the calculated melt-point of the area of highest current density. The pressures and impulses are quite different between the aluminum plate experiments and the copper-PCB experiments suggesting that the calculated meltbegin is a reliable metric for determining the excitation that will cause the onset condition.…”

“…This melt-competition theory of bifurcations also suggests that cuts could extend in more than two locations. This would explain the trifurcation that was observed in our previous publication [7] as well as the multiple cuts in [1].…”

This paper proposes that in some instances, the magnetic saw effect is purely a melt phenomena and describes a series of experiments where the magnetic saw effect was studied by varying the sub-millimeter radius of the enhancement point on a set of highly-controlled samples. The magnetic saw effect is an instability that can occur when high currents are required to make sharp bends, thereby greatly enhancing the magnetic field and current densities. These sharp bends generally occur at joints, cuts, or other flaws and can cause failure of high-current conductors. The magnetic saw effect has also been proposed as a possible metalcutting mechanism for manufacturing purposes. Due to the very small length scales of the features associated with magnetic sawing, it is difficult to make samples that are controlled enough to get reproducible experimental results for systematic studies. In these experiments, printed circuit board technology was used to accurately make samples with very fine enhancement features. The conditions for the magnetic saw effect were modeled using an electromagnetic code to establish the important parameters that predict the onset of damage.
