高应变率下的岩石动载特性

The Dynamic Behavior of Magnetites and Granite under High Strain Rates

    摘要
  • 摘要: 采用先进的霍布金生杆(SHPB)装置对多种矿岩进行了高应变率下(ε=300～1000s-1)的力学特性研究。给出了矿岩在不同应变率下的动态破坏强度、动态弹性模量、动态应力-应变曲线和分析结论。

     

    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.
