T. LAUWAGIE, Vibration-based methods for the identification of the elastic properties of layered materials, 2005

Abstract

This thesis develops a vibration-based identification technique to determine the elastic properties of the constituent layers of layered materials. The presented mixed numerical-experimental technique (MNET) derives the layer properties from the resonant frequencies of rectangular beam- or plate-shaped specimens, and is able to identify the in-plane elastic properties of both isotropic and orthotropic materials. An optional post-processing step allows the estimation of the uncertainty of the identified elastic parameters.

The thesis comprises three main parts. The first part, chapters 1 to 4, introduces the mathematical tools that are required to construct an MNET procedure. The second part, chapters 5 to 7, uses these mathematical tools to build a series of vibration-based identification procedures for the identification of the elastic properties of layered materials. The last part, chapters 8 and 9, provides an experimental validation together with a number of applications of the developed identification routines.
