| Popis: | Appropriate sensors and measuring systems are required to gather information on the fatigue state of technical devices and predict their residual life and reliability. We consider the possibility of using bonded foils, made of ferromagnetic materials, for creating wireless primary transducers of fatigue hours of a structure member. It is shown that when subjected to fatigue loading, 20–40 μm–thick foils made of nickel and 50NP and 79NM alloys considerably change their electromagnetic properties and can thus be used in the future to develop fatigue sensors. |
