Corrosion assessment of structural components using electro mechanical impedance

Rapid innovation in interdisciplinary technology emphasized the data acquisition system to evaluate structural integrity by combining with advance sensing techniques. These smart sensors impedance methodology has shown an excellent potential assessing health condition and provided alternative many sophisticated Non destructive monitoring systems. The sensitivity of electro mechanical technique detecting local incipient damages is enhanced piezoelectric mechanism lead zirconate titanate materials conductance signatures these can determine dynamic variations properties more effectively. In present work numerical finite element analysis conducted on simply supported RCC beam Abaqus software reinforcement subjected corrosion five stages different reduction rates coupled transducers along length implement strategy. surface bonded patches are electrically excited external voltage under specific frequency range conduct linear perturbation harmonic output responses healthy corroded beams from sensor locations captured compared. peak shifting nature signature pattern will serve as indicator diagnose severity propagation components. simulation results proposed showed feasibility employing identify activity members electromechanical conductivity signatures.
