Abstract: Temperature and external load are two important factors affecting the mechanical properties of rock material. The test on heattreated granite specimen was carried out by using an improved split Hopkinson pressure bar (SHPB). Based on the test data, the dynamic behavior and failure characteristics of the granite under the coupling action of temperature and impact loading are studied. The results show that the amplitude of incident wave increases with the impact velocity of striker, and the shapes of the transmi…
