Study on the Dynamic Mechanical Properties of

In order to study the dynamic mechanical properties of metamorphic limestone under different strain rates, a reasonable impact air pressure must be determined before the impact test. Different impact air pressures are used to achieve different impact speeds of bullets to analyze the failure of rock specimens under different strain loading rates.
