Abstract

Travel on the road from schedule-based nondestructive inspection (NDI) to structural health monitoring (SHM) has been productive, but the destination has not yet been reached. NDI is a generic descriptor that encompasses the application of numerous techniques, which can be used both in schedule-based inspection, on-site or in a maintenance facility, or in SHM with permanently installed sensors for continuous or on-demand inspection. Experimental ingenuity, improved hardware, analytical simulation techniques, use of statistical methods and improved signal processing techniques have produced significant progress in NDI. On the other hand, SHM has not yet broken through in a big way. Among the impediments, SHM systems are not yet affordably maintainable, with near-zero false alarm rates. Huge benefits can, however, be achieved if SHM can justify reduced design margins, longer life spans and reduced service interruptions of structural systems. SHM is a work in progress.
