Abstract: This thesis develops a vibration-based identification technique todetermine the elastic properties of the constituent layers of layeredmaterials. The presented mixed numerical-experimental technique (MNET)derivesthe layer properties from the resonant frequencies of rectangular beam-or plate-shaped specimens, and is able to identify the in-plane elasticproperties of both isotropic and orthotropicmaterials. An optional post-processing step allows the estimation of the uncertainty of the identified elastic parameters.Thethesis comprises three main parts. The first part, chapters 1 to 4,introduces the mathematical tools that are required to construct anMNET procedure. The second part, chapters 5 to 7, uses thesemathematicaltools to build a series of vibration-based identification proceduresfor the identification of the elastic properties of layered materials.The last part, chapters 8 and 9, provides an experimentalvalidation together with a number of applications of the developed identification routines.
