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.

The proposed book will offer comprehensive and versatile methodologies and recommendations on how to determine dynamic characteristics of typical micro- and opto-electronic structural elements (printed circuit boards, solder joints, heavy devices, etc.) and how to design a viable and reliable structure that would be able to withstand high-level dynamic loading. Particular attention will be given to portable devices and systems designed for operation in harsh environments (such as automotive, aerospace, military, etc.) In-depth discussion from a mechanical engineer's viewpoint will be conducted to the key components’ level as well as the whole device level. Both theoretical (analytical and computer-aided) and experimental methods of analysis will be addressed. The authors will identify how the failure control parameters (e.g. displacement, strain and stress) of the vulnerable components may be affected by the external vibration or shock loading, as well as by the internal parameters of the infrastructure of the device. Guidelines for material selection, effective protection and test methods will be developed for engineering practice.
