Originální abstrakt

This paper introduces a new method of pulsed acoustic Barkhausen noise for stress detection and material characterisation. Pulsed excitation can provide wide spectral components and time information for non-destructive evaluation and material characterisation. After introducing the system set-up, several experiments including stress variation and residual stress orientation are outlined, in comparison with magnetic field intensity measurement. Different Barkhausen noise and magnetic acoustic emission characterisation methods such as Root Mean Square (RMS), absolute energy and event count are discussed and a new quantitative method for pulsed acoustic Barkausen noise and magnetic flux leakage is investigated for stress detection and material characterisation.
