RESEARCH ON SHPB TESTING TECHNIQUE FOR BRITTLE MATERIAL
脆性材料SHPB实验技术的研究

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.
