Magneto-Mechanical Effects Under Low Fields and High Stresses— Application to a Ferromagnetic Cylinder Under Pressure in a Vertical Field

This study focuses on the effects that a ferromagnetic material undergoes when subjected to high stresses under low magnetic field. In order to predict the magnetic signature, we show that the Jiles magnetization law of approach can be applied to model induction measured by external sensors, and an analytical solution is derived in the case of our prototype, a cylinder subjected to an internal pressure up to 100 Bars in a vertical field. Comparison between model predictions and measurements shows an error lower than 5%.
