Abstract
The results of measurement of the root-mean-square voltage of Barkhausen noise (BN) and the amplitudes of the first three harmonics of the BN-voltage envelopes of flat cross-shape steel St. 3 and steel 20 specimens in biaxial tension are presented. The possibilities of determining the principal stresses by the magnetic-noise method using curves of constant BN parameters in the plane of the principal stresses are demonstrated.
