Abstract

A split-Hopkinson bar, or Kolsky bar, is now a classical characterization technique for determining the dynamic mechanical properties of many materials, such as metals, ceramics, polymers, and composites. The materials are usually deformed at high strain rates of 102–104s−1. This chapter first introduces the brief history, general working principles and procedures, requirements, and design of various mechanical experiments by using the Kolsky bar technique. Afterward, the recent advances in Kolsky bar technique, its integration with advanced imaging techniques for characterizing the dynamic behavior of materials, and the new trends are presented.
