Mechanical spectroscopy is a non-desctructive 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 50 years, and in this textbook aims at summarizing the state-of-the-art in this field by presenting results obtained by Western European laboratories. spectroscopy (Ch. 1) is basedon a complete description of elastic, viscoelastic, and viscoplastic behaviour of solids. The anelastic response is analyzed from three different veiwpoints: phenomenology, rheology and thermodynamics. 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. as thin-layers, localized surface properties, stress relazation 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.
