Preface The objective of this book is to provide the readers with a working knowledge of dynamic experiments with a Kolsky bar, also widely known as a split Hopkinson pressure bar (SHPB). Kolsky bar has been extensively used for the characterization of material properties at high rates, where the results are a family of stress-strain curves with the strain rate as a parameter. Unlike quasi-static experiments for constitutive responses of materials, there is no standard approach currently available to measure the responses at high rates of deformation. Consequently, inconsistencies may exist in the results generated from different laboratories, with different bars, and by different operators. This book provides practical guidelines to design and perform Kolsky-bar experiments. The focus is on the improvement of experimental consistency using methods that facilitate the specimen to deform under desirable valid testing conditions. This book is not an extensive review of the Kolsky-bar technique. A number of review articles are available in literature. Rather, this book illustrates the design, execution, evaluation and application of Kolsky-bar experiments in details. The presented topics start with the general concepts and fundamental principles of the Kolsky bars; followed by the design guidelines for various types of Kolsky-bar experiments; ranging from compression experiments on brittle, soft, and ductile materials; to experiments under multiaxial compression and at high/low temperatures; to tension/torsion experiments; as well as to int
