    Rock dynamics has become one of the most important topics in the field of rock mechanics and rock engineering. The spectrum of rock dynamics is very wide and it includes the failure of rocks, rock masses and rock engineering structures such as rockbursting, spalling, popping, collapse, toppling, sliding, blasting, non-destructive testing, geophysical explorations, science and engineering of rocks and impacts. The book specifically covers fundamentals of rock dynamics, constitutive models, numerical analysis techniques, dynamic testing procedures, the multi-parameter responses and motions of rocks during fracturing or slippage in laboratory experiments, earthquakes and their strong motion characteristics and their effect on various rock structures such as foundations, underground structures, slopes, dynamic simulation of loading and excavation, blasting and its positive utilization in rock engineering, the phenomenon of rockburst in rock excavations, non-destructive testing of rockbolts and rock anchors and impacts by meteors or projectiles. The main goal of this book is to present a unified and complete treatise on Rock Dynamics and to represent a milestone in advancing the knowledge in this field and in leading to new techniques for experiments, analytical and numerical modelling as well as monitoring of dynamics of rocks and rock engineering structures.

    Dr. Omer Aydan was born in 1955, and studied Mining Engineering at the Technical University of Istanbul, Turkey (B.Sc., 1979), Rock Mechanics and Excavation Engineering at the University of Newcastle upon Tyne, UK (M.Sc., 1982), and finally received his Ph.D. in Geotechnical Engineering from Nagoya University, Japan in 1989. He worked at Nagoya University as a research associate (1987-1991), and at the Department of Marine Civil Engineering at Tokai University, first as Assistant Professor (1991-1993), then as Associate Professor (1993-2001), and finally as Professor (2001-2010). He then became Professor of the Institute of Oceanic Research and Development at Tokai University, and is currently Professor at the University of Ryukyus, Department of Civil Engineering & Architecture, Nishihara, Okinawa, Japan. Omer has played an active role on numerous ISRM, JSCE, JGS, SRI and Rock Mech. National Group of Japan committees, and has organized several national and international symposia and conferences. He was also made Honorary Professor in Earth Science by Pamukkale University in 2008.

    "The publication of this book is timely and welcome by the rock mechanics and rock engineering community.

    The book is a good reference book for people involved in rock dynamics and earthquake geotechnical engineering. It will enlarge and deepen their knowledge to develop more efficient techniques in rock dynamics. The book is meant to be a reference book given its continued focus on practical solutions rather than basic fundamentals."

    Prof. Giovanni Barla, Vice President of ISRM 1995-1999. Reviewed in the February 2018 issue of the Rock Mechanics and Rock Engineering Journal.
