Abstract: This paper presents a strain evaluation of mild steel plates by attractors constructed from Barkhausen noise. The strain of magnetic materials affects the magnetic domain. Hence the strain can be evaluated by Barkhausen noise. Barkhausen noise from magnetic materials is a very complicated non-linear wave. Thus Barkhausen noise is examined before and after the tensile stress by attractors to make clear the chaotic behaviour to use it for the strain evaluation.
