Materials processing using explosion, shock-wave and high-strain-rate phenomena was developed after WWII, and these explosive forming and welding techniques have since been adopted as an accepted industrial technology. Such extremely high-rate phenomena historically used empirical experiences while the experimental conditions were not well documented due to the difficulties inherent in understanding the real response or behaviour of materials. Based upon the recent development of numerical techniques for analysis and the enriched data available on the behaviour of materials, it is now possible to predict such high-rate phenomena based upon numerical and experimental approaches including optical observation. Explosion, Shock-wave and High-strain-rate Phenomena of Advanced Materials demonstrates the deformation of various materials at high-rate based upon numerical analysis and supported by experimental evidence. The book is recommended for researchers and engineers who would like to learn more about the high-rate effect of materials and those who need to resolve multi-physics problems based on numerical approach. It is also ideal for researchers and engineers interested with explosive and other high-rate processing of materials.
- Presents numerical techniques on the analysis and enriched data on the behavior of materials based upon a numerical approach
- Provides case studies to illustrate the various methods discussed
- Includes mechanical response at high-rates of porous materials

Kazuyuki Hokamoto is a professor of the Shock Wave and Condensed Matter Research Center, Kumamoto University with the Institute of Pulsed Power Science. After finishing his Doctorate program at Kyushu University, Japan, Dr. Hokamoto held an Assistant Professor position at the Department of Mechanical Engineering, Kumamoto University. In addition, he served as a visiting scholar at UC San Diego and Georgia Tech. During his more than 30 year academic career, he has been engaged in research on the use of explosive and other impulsive energies for materials processing and has been published in many papers in academic journals. He received the best paper award in 2004 from JSTP (Japan Soc for Technology of Plasticity) and he is currently serving as a chairman of the committee on the High-Energy-Rate Forming of JSTP since 2009. Due to his unique research field engaged, he has been organized ESHP (Explosion, Shock-wave and High-strain-rate Phenomena) symposium series 2003 to 2019 for 6 times.
