TORSION AND STRESS EFFECTS AND MODELING IN POSITIVE MAGNETOSTRICTIVE WIRES

Results on torsional and tensile stress dependence in amorphous magnet ostrictive Fe-rich wires used as magnetostrictive delay line are repor ted in this paper, The obtained results show a not monotonic dependenc e of the pulsed voltage output on the applied torsion along the length of the amorphous wire and a monotonic dependence for applied tensile stress. The dynamic modelling of the outer shell behaviour in positive magnetostrictive wires, under stress and torsion, is consequently ana lyzed.
