While overloading can produce severe but recoverable changes in modal properties, in the order of 30%, environmental conditions like temperature and humidity can produce state changes, parti

The issues discussed in this chapter include the purpose of the test, excitation considerations, response measurements, support conditions, measurement quality criteria, and consider

H. Hamperl,E. Hecker,C. G. Schmidterived substructures to estimate the system response of the coupled substructures. A unifying theoretical framework in the physical, modal or frequency domain is reviewed with examples. The major issues that have hindered experimental based substructures are addressed. An example is demonstrated wit

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

Andreas Vogel,Christina Holtz-Bachalops the frequency response function from the perspective of experimentally measured system excitations and responses. Experimental measurement and numerical processing techniques are presented that allow minimization of the impact of measurement noise and signal processing errors.

For random vibrations, correlation functions and their frequency counterparts, spectral densities, are the tools used to
