Chapter 6: DAMAGE DETECTION ON A MASSIVE STEEL HEADER

A preliminary set of experiments was to be conducted on a massive steel steam header. The possibility of implementing the impedance-based health monitoring technique to detect damage on large, dense structures was to be investigated. Practical issues such as positioning of the PZT’s, optimal frequency level and range, and the extent of damage that could be detected were the issues that were dealt with. The main aim of this experiment was to conduct an initial study that could then lead to a more detailed analysis.
