| Abstract: | Split Hopkinson's Pressure Bar has been used to study the dynamic beva-vior of three kinds of magnetites and one granite at strain rates ranging from 300 to 1000s-1. Some results including the dynamic fracture strength, Young's modulus, stress-strain curve and constitutive equations of the rocks are given in this paper. |

| Keywords: | strain rates dynamic fracture strength dynamic constitutive equation. |
