| 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. |
