The dynamic characteristics in higher strain rate of brittle materials, such as hard rock, concrete, mortar and ceramics with high strength, and the non-homogeneous structural materials consisting of brittle material are researched using SHPB device. The progress is brought about in SHPB testing technique. The problems are discussed briefly of gimbals, pulse shaper, non-uniform linear projectile, soft medium on the impacted end of the input bar, artificial joint sample and structural material sample.
