Bücher der Reihe Shock Wave and High Pressure P

This book compiles historical notes and a review of the work of the author and his associates on shock compression of condensed matter (SCCM). The work includes such topics as foundational aspects of SCCM, thermodynamics, thermodynamics of defects, and plasticity as they relate to shock compression, shock-induced phase transition, and shock compaction. Also included are synthesis of refractory and hard ceramic compounds such as Ni aluminides, SiC and diamonds, method of characteristics, discrete element methods, the shock compression process at the grain scale, and modeling shock-to-detonation transition in high explosives.The book tells the story of how the author's view of shock physics came to be where it is now. and analytically discusses how the author's appreciation of shock waves has evolved in time. It offers a personal but pedagogical perspective on SCCM for young scientists and engineers who are starting their careers in the field. For experts it offers materials to nudge them reflect on their own stories, with the hope of planting a seed of motivation to write them down to be published.

This book offers an interdisciplinary theoretical approach based on non-equilibrium statistical thermodynamics and control theory for mathematically modeling shock-induced out-of-equilibrium processes in condensed matter. The book comprises two parts. The first half of the book establishes the theoretical approach, reviewing fundamentals of non-equilibrium statistical thermodynamics and control theory of adaptive systems. The latter half applies the presented approach to a problem on shock-induced plane wave propagation in condensed matter. The result successfully reproduces the observed feature of waveform propagation in experiments, which conventional continuous mechanics cannot access. Further, the consequent stress-strain relationships derived with relaxation and inertia effect in elastic-plastic transition determines material properties in transient regimes.

This book offers historical and state-of-the-art molecular spectroscopy methods and applications in dynamic compression science, aimed at the upcoming generation in physical sciences involved in studies of materials at extremes. It begins with addressing the motivation for probing shock compressed molecular materials with spectroscopy and then reviews historical developments and the basics of the various spectroscopic methods that have been utilized. Introductory chapters are devoted to fundamentals of molecular spectroscopy, overviews of dynamic compression technologies, and diagnostics used to quantify the shock compression state during spectroscopy experiments. Subsequent chapters describe all the molecular spectroscopic methods used in shock compression research to date, including theory, experimental details for application to shocked materials, and difficulties that can be encountered. Each of these chapters also includes a section comparing static compression results. The last chapter offers an outlook for the future, which leads the next-generation readers to tackling persistent problems.
