Abstract
This paper shows determination of elastic constants of thin layers deposited on substrates. Resonant ultrasound spectroscopy is used to measure resonant spectras before and after layer deposition. These two spectra are compared and changes in the position of the resonant peaks are associated with layer properties. For thin layers either the elastic moduli or the surface mass density can be determined, providing the complementary information.
