Influence of biaxial stress on magnetostriction—Experiments and modeling

The paper deals with the influence of biaxial stress on the magnetic and magnetostriction behavior of a low carbon steel used for structural pieces in the car industry. Material, specimen, measurement setup and protocol are presented. Anhysteretic measurements are performed, giving results in accordance with literature. A quadratic approximation of magnetostriction vs. induction measurements allows the evaluation of a single magnetostriction parameter per mechanical state. Results are compared to the outputs of a multiscale model, which indicate coherent tendencies but some significant amplitude differences.
