To extend pulse calorimetry to selected mechanical properties, NIST has developed a new apparatus called the pulse-heated Kolsky bar, or split-Hopkinson pressure bar apparatus [127, 128]. The combination of the two techniques produces high-rate dynamic loading, while simultaneously pulse heating the specimen with electrical current.

Dynamic mechanical experiments were completed with SHPB test device from China University of Mining and Technology (Beijing), The Split Hopkinson Pressure Bar (SHPB) is currently widely used to study dynamic strain rate. Using cp50 mm SHPB test device, dynamic mechanical properties of coal and limestone under different strain rates were analyzed and mechanical properties of coal and limestone were explained from the structure. 

The impact experiments of anthracite and limestone samples were conducted by using 4>50 mm split Hopkinson pressure bar (SHPB) experiment system, the dynamic mechanical properties of samples are analyzed under impact loading. Finally, the relationship between the dissipation energy and impact velocity is studied. The main conclusions are as follows.
