A multiscale model for piezomagnetic behavior Coupled anhysteretic multiscale and hysteretic Jiles-Atherton approaches

Abstract : This work is concerning the development of a stress sensor for high strain rate applications (Hopkinson bar apparatus). The physical principle of the sensor is based on the piezomagnetic behavior of remanent magnetic material. Experiments consist in anhysteretic and hysteretic piezomagnetic measurements of a low carbon steel. We then propose a model for the piezomagnetic behavior based on a modified formulation of Jiles model and a multi-scale model for the anhysteretic part. Modeling and experiments are in good agreement.
