by Lee Davison (Author)
This book is an introduction to the thermomechanical theory required to conduct research and pursue application of shock physics in solid materials. It is the first textbook devoted entirely to shock physics of solid materials. Emphasis is on a regime where solids can be described as elastoplastic materials. The main text is complemented with numerous exercises and solutions. The book itself falls naturally into four parts, with a first part exposing the principles of both continuum mechanics and plane longitudinal shocks. The following four chapters treat various aspects of materials response. The third part of the book deals with linear and nonlinear wave propagation in such media and the fourth part introduces a number of advanced topics, such as porous solids, spall fracture and the detonation phenomenon. This book provides a reference and tutorial for an interdisciplinary field with applications ranging from astrophysics and geophysics to materials science, aeronautics, and semiconductors.

This book forms an introduction to important aspects of shock-wave propagation in solid materials. Emphasis is on the regime of moderate compression that can be produced by high-velocity impact or detonation of chemical explosives. In this regime relatively simple equations of state are applicable to the description of compression. Solids may also experience inelastic flow, in which elastic-plastic deformation becomes important. The theory provided is that required to conduct research in the field and to pursue its application to ordnance development, Earth and planetary sciences, materials research, and other matters. The book includes a careful account of the kinematical and dynamical equations of the subject along with constitutive equations that describe the distinguishing responses of compressible fluids, elastic solids, and elastic-plastic and elastic-viscoplastic solids. The discussion of wave propagation begins with elementary analyses of important problems of the propagation and interaction of plane longitudinal shocks. This is followed by more refined analyses of problems of plane-wave propagation in the aforementioned materials. Finally, spall fracture, wave propagation in porous solids, and detonation phenomena are discussed. Many illustrative problems can be solved without recourse to extensive numerical analysis. The text includes numerous exercises and detailed solutions to these exercises.
