METHOD FOR DETECTING THE MECHANICAL STRESS TO WHICH A PART MADE OF A MAGNETOSTRICTIVE MATERIAL IS SUBJECTED

摘要

The invention relates to a method for detecting the stress to which a part made of a magnetic material having a detectable magnetostriction property, such as a ferromagnetic material, is subjected, including the following steps: (a) applying variable stress to the part (32); (b) measuring the magnetic field (B) near the part (32) during the application of the variable stress to the part; and (c) comparing (34) the measurement to a reference measurement.
