The Kolsky compression bar, or split Hopkinson pressure bar (SHPB), is an ex- perimental apparatus used to obtain the stress-strain response of material specimens at strain rates in the order of 10 2 to 10 4 1/s. Its operation and associated data re- duction are based on principles of one-dimensional wave propagation in rods. Second order effects such as indentation of the bars by the specimen and wave dispersion in the bars, however, can significantly affect aspects of the measured material response. Finite element models of the experimental apparatus were used here to demonstrate these two effects. A procedure proposed by Safa and Gary (2010) to account for bar indentation was also evaluated and shown to improve the estimation of the strain in the bars significantly. The use of pulse shapers was also shown to alleviate the effects of wave dispersion. Combining the two can lead to more reliable results in Kolsky compression bar testing.

The authors systematically describe the general principles of Kolsky bars, or split Hopkinson bars, which are widely used for obtaining dynamic material properties. Modifications are introduced for obtaining reliable data. Specific experiment design guidelines are provided to subject the specimen to desired testing conditions. Detailed Kolsky-bar examples are given for different classes of materials (brittle, ductile, soft, etc) and for different loading conditions (tension, torsion, triaxial, high/low temperatures, intermediate strain rate, etc). The Kolsky bars used for dynamic structural characterization are briefly introduced. A collection of dynamic properties of various materials under various testing conditions is included which may serve as a reference database. This book assists both beginners and experienced professionals in characterizing high-rate material response with high quality and consistency. Readers who may benefit from this work include university students, instructors, R & D professionals, and scholars/engineers in solid mechanics, aerospace, civil and mechanical engineering, as well as materials science and engineering.

In this book, leading scientists share their vision on the Kolsky-Hopkinson bar technique, which is a well-established experimental technique widely used to characterize materials and structures under dynamic, impact and explosion loads. Indeed, the Kolsky-Hopkinson bar machine is not a simple experimental device. It is rather a philosophical approach to solve the problem of measuring impact events. The split Hopkinson pressure bar conventional device is mainly limited to test homogeneous ductile non-soft materials under uni-axial compression. Extending the use of this device to more versatile applications faces several challenges such as controlling the stress state within the specimen and mastering the measurement of forces and velocities at the specimen-bar interfaces and then the material properties. Thus, the topics discussed in this book mainly focused on the loading and processing parts.

Damage to critical energy infrastructure as a result of terrorism, criminal activity or natural disaster can have a significant impact at both a national and international level. Reducing the vulnerability of critical infrastructure to protect populations is therefore a high priority for governments worldwide, and high-quality training courses and advanced technologies are imperative in this regard. This book presents edited contributions from the NATO Advanced Training Course (ATC) entitled ‘Critical Energy Infrastructure Protection: Innovative Structures and Materials for Blast and Ballistic Protection’, held as a virtual event from 22 - 25 March 2021. The principal aim of the course was to gather specialists from NATO member and partner countries interested in protecting their critical infrastructure against terrorist attacks, and to share research and practical experience in this field. The meeting provided a forum for participants and speakers to disseminate their recent work, and also served to promote the exchange of ideas and international cooperation among scientists and engineers. The focus was on the physical protection of critical infrastructure in the face of certain types of intentional threat or accident, such as explosions, impacts and blast waves, and the experts shared their experience on topics including the mitigation of risks, classification of vulnerabilities, improvement of resilience, advanced protective materials, dynamic testing of materials and structures, simulations, and numerical prediction methods. The book will be of interest to all those whose work involves protecting critical infrastructure from the threat of terrorist attacks.
