APPLICATION OF MAGNETIC MICROWIRES FOR SENSING STRESSES IN STRUCTURES

Rudolf Sabol – Marian Rovnak – Viktoria Bajzecerova – Pavol Vojtanik – Rastislav Varga

   The possibility of application of glass-coated microwires for sensing stress in timber structure have been studied. The meas-urements of the switching field dependence on applied stress have been compared to the classical method of strain measure-ment - by the digital deformeter Huggenberger and resistance strain gauges. The test results obtained by using microwires proved to be consistent with those for which con-ventional strain gauges were used. However, it was found that the sensing is strongly influenced by the position of the excitation coil.
