Multiscale Mechanics of Shock Wave Processes (eBook)

This book presents theoretical and experimental investigations of mechanical behavior of solids under shock loading and highlights a multi-scale exchange process of energy and momentum between meso and macroscopic hierarchy. It also widely covers experimental approaches for the multi-scale response of solids to impacts including uniaxial strain conditions and high-velocity penetration processes.

The content comprises two parts. The first part overviews modeling and theory of dynamically deformed solids from the multi-scale point of view. The second part describes experimental characterization of shock-induced solids and experimental probing of mesostructured and mesoscale dynamic processes in solids. The theory presented in the first part is then verified as it is compared with i) experiments of shock loading into different kinds of solids and ii) probed microstructure of post-shocked specimens by scanning electron microscopy, transmission electron microscopy and optical microscopy.

The text is written on the basis of author's lectures at universities and thus is concisely described for postgraduate students. It is also useful for researchers who work on the theory of multi-scale mechanics of solids and engineers who work on testing materials under dynamic loading.

Yurii Meshcheryakov is a professor and a laboratory head at the Institute of Problems of Mechanical Engineering, Russian Academy of Science. His work is widely concerned with investigation and characterization of materials under shock loading and shock wave propagation in condensed matter. He received his Ph.D. degree in solid physics from the State Institute of Special Devices 'Granit', Saint Petersburg, in 1967, and his Doctor of Science degree in physics-mathematical sciences, mechanics, and physics of solids from Saint Petersburg State University in 1984. He moved to his current affiliation as a laboratory head in 1986 and has been a professor there since 1994. He was given an Honored Scientist of the Russian Federation Award in 2000 and the Medal In Commemoration of the 300th Anniversary of Saint Petersburg in 2003.
