摘要
用SHPB装置研究脆性材料(硬岩、混凝土、高强度砂浆、陶瓷等)及脆性材料组构的非均一材料高应变率下的动力特性。在实验技术方面取得进展,简要研讨了万向头、波形整形器、异形炮弹、软性介质、节理试样与结构性试样等问题。
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.
