A Short Note on Simulation of Soft Ferromagnetic Materials

Author(s): Velten Fletcher

Electrical resistivity measurement is widely used to evaluate the self-sensing capability of conductive fiber-reinforced cement composites and to characterize various phases of cement composites. In order to investigate the properties of cement composites, the electrode parameters, including material, layout, and fixing style, need to be carefully chosen because the electrodes play a significant role in measuring the resistivity. The electrical behavior of cement mortars was evaluated and contrasted using three distinct materials as electrodes in this investigation. The desired electrode material was identified by qualitatively comparing the results in terms of resolution, sensitivity, and noise fluctuations. In addition, the polarization and depolarization zones of specimens containing various fractions of silica fume were examined in order to evaluate the effect of silica fume on the measured values. As demonstrated by the results, the percentage of silica fume replacement had an effect on electrical polarization and depolarization, making brass an appealing option for use as an electrode due to its short response time and low current fluctuations.
