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.
