-
摘要: 采用先進的霍布金生桿(SHPB)裝置對多種礦巖進行了高應變率下(ε=300～1000s-1)的力學特性研究。給出了礦巖在不同應變率下的動態破壞強度、動態彈性模量、動態應力-應變曲線和分析結論。Abstract: Split Hopkinson's Pressure Bar (SHPB) has been used to study the dynamic behavior of three hinds of magnetics and one granite at strain rates rangingfrom 300 to 1000 s-1. Some results including the dynamic fracture strength, Yaung's modulus, stress-strain curve and constitutive equations of the rocks are given.
