Model reduction and model expansion techniques are presented first. Correlation tools typically deployed are then presented. Some additional commentary related to the tes

The sensitivity method described in this chapter has been implemented numerous times in commercial codes and applied successfully in industry. It has become a mature technology in regular use in the automotive and

Experimental structural dynamics began much earlier with analog, single frequency data acquisition and mostly visual data processing that began in the 1800s with the rail and marine industries, particul
