Abstract
This paper presents a tensile stress evaluation of steel plates by chaos of Barkhausen noise. The stress of magnetic materials affects magnetic domains, so the amount of the stress can be evaluated by Barkhausen noise. Barkhausen noise is a very complicated signal, so a special evaluation method is needed to use it. The quantitative change of Barkhausen noise after a tensile stress test can be found by the fractal dimension of the chaotic attractors constructed by the measured Barkhausen noise.
