Abstract (EN): The efficiency of the use of magneto-elastic effect for stress evaluation and defect detection on steel strands is studied. Static and dynamic tests on seven-wire strands were conducted. Magneto elastic transducers were used to evaluate the applied stress related to the magnetic permeability. The results are compared with those obtained by fiber optic sensors installed on the strands and the ones obtained indirectly from identification of natural frequencies associated with the strands vibration. The detection of corrosion and other surface defects by magneto-elastic effect is also investigated.
