Über dieses Buch

This book serves as a self-contained reference source for engineers, materials scientists, and physicists with an interest in relaxation phenomena. It is made accessible to students and those new to the field by the inclusion of both elementary and advanced math techniques, as well as chapter opening summaries that cover relevant background information and enhance the book's pedagogical value. These summaries cover a wide gamut from elementary to advanced topics.
The book is divided into three parts. The opening part, on mathematics, presents the core techniques and approaches. Parts II and III then apply the mathematics to electrical relaxation and structural relaxation, respectively. Part II discusses relaxation of polarization at both constant electric field (dielectric relaxation) and constant displacement (conductivity relaxation), topics that are not often discussed together. Part III primarily discusses enthalpy relaxation of amorphous materials within and below the glass transition temperature range. It takes a practical approach inspired by applied mathematics in which detailed rigorous proofs are eschewed in favor of describing practical tools that are useful to scientists and engineers. Derivations are however given when these provide physical insight and/or connections to other material.

Mathematics

Frontmatter
Chapter 1. Mathematical Functions and Techniques
Abstract
This chapter summarizes many of the mathematical functions and techniques required to analyze relaxation phenomena quantitatively. Elementary mathematical results are given in Appendix B, and additional specialized results are presented in Chaps. 2, 3 and 5. Elementary statistics is briefly summarized in Chap. 4.
Ian M. Hodge
Chapter 2. Complex Variables and Functions
Abstract
Complex numbers and functions are discussed. This material lays the groundwork for fundamental relaxation results.
Ian M. Hodge
Chapter 3. Other Functions and Relations
Abstract
This chapter describes mathematics that are specifically applicable to relaxation phenomena but not restricted to the frequency domain. In particular Sect. 3.7 gives fundamental derivations of relations between frequency domain functions and relaxation time distributions.
Ian M. Hodge
Chapter 4. Elementary Statistics
Abstract
This chapter describes elementary statistical functions and techniques that apply to the analyses of experimental data. Statistics is probably second in subtlety only to thermodynamics (Chap. 10).
Ian M. Hodge
Chapter 5. Relaxation Functions
Abstract
This Chapter mainly reviews specific (and with one exception empirical) complex relaxation functions and distributions of relaxation times used to analyze experimental relaxation data. The Chapter also summarizes basic relaxation concepts such as Boltzmann superposition and thermorheologucal complexity (temperature dependent relaxation parameters).
