英文摘要：

The split Hopkinson pressure bar （SHPB） experimental technique is the most common method to evaluate the dynamic mechanical properties in the range of strain rates from 10^2s^-1 to 10^4s^-1. The state-of-theart methods in Hopkinson bar experiments are summarized after a detailed discussion of the three classic papers by Hopkinson, Davies, and Kolsky. Advancements of the Hopkinson bar experimental methods are discussed, including fundamental theories, loading techniques and improvements in measurements. Fndamentals of the Hopkinson bar experimental procedure are outlined, including specimen design, friction effect and pulse shaping. The loading techniques consist of pulse shaping, single-pulse loading and controlled multi-pulse loading. The quartz-crystal system, the laser system and the infrared system represent recent improvements in the SHPB experimental technique. This paper provides necessary information for conducting a Hopkinson bar experiment and analyzing the experimental data. It is essential to standardize the SHPB technique and apply it to even larger range of materials in the future.
