Barkhausen criteria

웹This paper deals with a multifeature numerical instrument for nondestructive testing of ferromagnetic materials, based on the Barkhausen noise. Starting from traditional instruments based on the root mean square value of the band-pass filtered measured signal, the proposed method is based on the simultaneous analysis of the excitation voltage, the excitation … 웹Another material monitoring technique arises from monitoring process conditions of the upstream processes, e.g., cold rolling, leading indirectly to insights on material properties. In this work, a systematic literature review (SLR) [2] is conducted to investigate recent approaches for material monitoring and for the utilization of resulting material data for …
