【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。更多还原

【Abstract】 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.更多还原
