| Abstract: | SHPB experimental technology, as an effective measure of materials′ dynamic mechanic characteristics, is widely used to the study of materials′ dynamic mechanical characteristics. This paper summarizes the investigation advance of SHPB technology systemically, it points out major problems existing in current study, as well as basic ideas of solution, including the principle, equipments and improvement of data procession. And it points out direct method and unbind-coupling method solve the problem on stress uniformity, flexible shapers minish wave dispersion , mathematics solve contact problems between ends. |
