Elastic waves in solids cause periodic surface deformations. These displacements can be examined both with time averaging shearography (qualitatively) as well as with vibrografie (quantitatively). Local defects such as delaminations behave like vibrating membranes and thus have their own resonant frequencies, which are usually significantly higher than the natural frequencies of the components. Vibrational excitation is also suited very well for very stiff materials such as ceramics.
