Mechanical Spectroscopy 2001
Mechanical spectroscopy is a non-destructive technique that is very well suited for studying the dynamics of singularities such as structural defects in solids. It has been successfully applied in solid state physics and materials science for more than fifty years, and the present textbook aims at summarising the state-of-the-art in this field by presenting recent results obtained in Western European laboratories. The contents are divided into nine chapters. Introduction to mechanical spectroscopy (Ch.1) is based on a complete description of the elastic, viscoelastic, and viscoplastic behaviours of solids. The anelastic response is analysed from three different viewpoints: phenomenology, rheology and thermodynamics.
Anelastic relaxations due to structural defects are treated according to the defect dimensionality: point defects (Ch. 2), one-dimensional defects, such as dislocations (Ch. 3), two-dimensional defects, such as grain boundaries (Ch. 4) or the surface of domains (Ch. 6). Mechanical losses associated with phase transitions are presented in chapter 5, and relaxation in non-crystalline materials in chapter 7. Applications of the technique to various domains of materials science, such as thin-layers, localised surface properties, stress relaxation in composites, fatigue and the development of high-damping materials, are described, with examples, in chapter 8. Chapter 9 covers classical, and new, techniques for measuring internal friction or ultrasonic attenuation in solids, from macro- down to nanoscale.
