Abstract
The magnetic Barkhausen effect is useful forassessing 1D and 2D stress states of ferromagnetic steelobjects. However, its extension to technically importantmaterials, such as duplex anisotropic steels, remains challenging. The determination of magnetisation inside the studied object and the electromagnet for various geometries, materials and magnetisation angles is a key issue.Three-dimensional, dynamic finite element analysis has beenapplied to reproduce time-varying fields inside and outsidethe prototype of a double-core magnetising setup. Useful relationships between characteristics (peak height and localtion) andmagnetic induction vector have been proposed. Thequalitative plausibility of simulation has been validated withan experiment and an analytic formula of skin depth. Theangular anisotropy of magnetic Barkhausen effect (MBN) inan isotropic sample has been shown in simulation and confirmed experimentally. The numerical model, despite somelimitations, seems to be an efficient tool for calibratingstress/MBN relationships at least in isotropic structural steelcomponents.
