Abstract

Infrastructure construction is the second largest economic activity in India after agriculture and it is growing rapidly.Structural Health Monitoring (SHM) aims to provide new solutions for easy and swift inspection of engineered structures.Electromechanical impedance (EMI) technique is a relatively new useful and convenient technique in the area of SHM.Though this technique shows promising results in the area of SHM, the main disadvantage of this technique is the brittleness ofthe piezo-electric (PZT) material. To overcome this problem, a new variant has recently emerged wherein a metal wire iscoupled with the PZT patch and then attached with the host structure. This paper primarily focuses on evaluating the metalwire based EMI technique for damage assessment of 2D structure. Test results show that the technique can effectively identifyand locate damage on a 2D structure.
