Material Properties under Intensive Dynamic Loading

This book is the result of collaboration between the Russian Federal Nuclear Center – All Russian Scienti? c Research Institute of Experimental Physics (RFNC-VNIIEF) located in Sarov, Russia and the University of California – Los Alamos National Laboratory (UC-LANL). The genesis of this project was the compilation of a set of lecture notes used by a number of leading VNIIEF researchers in courses taught to students of the Sarov Physical and Technical Institute(SarFTI)specializingin“Theoretical andExperimentalMechanics. ” A revised and signi? cantly supplemented version of those lecture notes was ultimately published as a monograph (in Russian) by VNIIEF Press, and is used today as a textbook in courses on shock mechanics being taught at SarFTI. Recognizing the potential bene? t of the manuscript to students and researchers in the ? eld of shock mechanics in the English-speaking world, a VNIIEF/LANL collaboration was established to revise/translate/update the manuscript. This book is the result of that e? ort. Understanding the physical and thermomechanical response of materials subjected to intensive dynamic loading is a challenge of great signi? cance in engineering today. When intensive dynamic loads, such as those that result from the detonation of high explosives (HE), high-velocity impact, or rapid localizedheating(suchasmightdevelopunderthee? ectsofincidentlaserlight or relativistic electron beam), are applied to condensed matter, the result is a complex pattern of material ? ow involving waves of discontinuous (shock) as well as continuous (expansion) nature. Shock compression (followed by expansion) precipitates both reversible and irreversible physical, physicochemical and mechanical processes in the material.
