This book presents, in a concise and comprehensive manner, the essential techniques by which shock wave physicists probe the boundaries of material response to impulsive loads. The author is a well-known figure in shock wave physics, having worked for over forty years with many of the outstanding researchers in the field.The book acquaints readers both with modern instrumentation techniques including interferometers such as the DISAR and the VISAR — and with methods that have been established by previous generations of experimentalists — including acoustic measurement techniques and low to moderate strain rate machines.Besides an exposition of the theoretical aspects of shock wave phenomena, it contains large amounts of data on equations of state, spallation thresholds, shock wave attenuation from very high pressures, and elastic constants. Much of this information has been previously unavailable in open publications.The text documents the transition from testing performed with explosives to the use of modern compressed gas guns, which permit much more detailed diagnostics and controlled conditions. In particular, the author pioneered the use of two-stage light gas guns which launch high-density plates against specimens located at the muzzle. The high launch velocity of these guns produced data that represents the highest pressures obtained in the free world at that time./a

This book presents a set of basic understandings of the behavior and response of solids to propagating shock waves. The propagation of shock waves in a solid body is accompanied by large compressions, decompression, and shear. Thus, the shear strength of solids and any inelastic response due to shock wave propagation is of the utmost importance. Furthermore, shock compres sion of solids is always accompanied by heating, and the rise of local tempera ture which may be due to both compression and dissipation. For many solids, under a certain range of impact pressures, a two-wave structure arises such that the first wave, called the elastic prescursor, travels with the speed of sound; and the second wave, called a plastic shock wave, travels at a slower speed. Shock-wave loading of solids is normally accomplished by either projectile impact, such as produced by guns or by explosives. The shock heating and compression of solids covers a wide range of temperatures and densities. For example, the temperature may be as high as a few electron volts (1 eV = 11,500 K) for very strong shocks and the densification may be as high as four times the normal density.

Dynamic Response of Advanced Ceramics Discover fundamental concepts and recent advances in experimental, analytical, and computational research into the dynamic behavior of ceramics In Dynamic Response of Advanced Ceramics, an accomplished team of internationally renowned researchers delivers a comprehensive exploration of foundational and advanced concepts in experimental, analytical, and computational aspects of the dynamic behavior of advanced structural ceramics and transparent materials. The book discusses new techniques used for determination of dynamic hardness and dynamic fracture toughness, as well as edge-on-impact experiments for imaging evolving damage patterns at high impact velocities. The authors also include descriptions of the dynamic deformation behavior of icosahedral ceramics and the dynamic behavior of several transparent materials, like chemically strengthened glass and glass ceramics. The developments discussed within the book have applications in everything from high-speed machining to cutting, grinding, and blast protection. Readers will also benefit from a presentation of emerging trends and directions in research on this subject as well as current challenges in experimental and computational domains, including: An introduction to the history of ceramic materials and their dynamic behavior, including examples of material response to high-strain-rate loading An exploration of high-strain-rate experimental techniques, like 1D elastic stress-wave propagation techniques, shock waves, and impact testing Discussions of the static and dynamic responses of ceramics and the shock response of brittle solids An overview of deformation mechanisms during projectile impact on a confined ceramic, including damage evolution during the nonpenetration and penetration phases. Perfect for researchers, scientists, and engineers working on ballistic impact and shock response of brittle materials, Dynamic Response of Advanced Ceramics will also earn a place in the libraries of industry personnel studying impact-resistant solutions for a variety of applications.

The book concerns the dynamic response of materials due to intensive impulsive loadings. The materials considered are primarily solids, although most of the discussions are also applicable to fluids. The loading and response in general happen within a very short time, in the order of microseconds, rather than milliseconds. The duration of the loading, whether mechanical impact or thermodynamic energy input, may sometimes be described in terms of nanoseconds. The magnitude of the loading is such that the initial stress in the material is high, and subsequently decays to moderate values, so that both compressibility and strength effects are important. The book is concerned only with material response, and not with structural response.
