Abstract To deeply compare and analyze the dynamic mechanics and failure characteristics of sandstone and quasi-sandstone, the impact compression and impact splitting tests of sandstone and quasi-sandstone were carried out with the help of the split Hopkinson pressure bar (SHPB) and RFPA^2D numerical calculation software. In the aspect of dynamic mechanics, the evolution characteristics and mechanism of stress-strain curves for sandstone and quasi-sandstone, the change characteristics of peak stress, dynamic increase factor (DIF), and ultimate strain with average strain rate, and the change characteristics of damage energy with incident energy were compared and analyzed. In the aspect of failure characteristics, the failure modes and damage mechanisms of sandstone and quasi-sandstone were compared and analyzed from macroscopic and mesoscopic levels. Combined with the damage variables defined by damage energy, the dynamic damage evolution characteristics of sandstone and quasi-sandstone were effectively described. The results show that although the quasi-sandstone prepared in the test can better reflect the dynamic mechanical law and damage-failure characteristics of sandstone to some extent, there were obvious differences in impact compression between them. The failure modes and damage evolution characteristics of sandstone and quasi-sandstone under SHPB numerical impact tests were basically consistent with those of SHPB physical impact tests, which confirmed the effectiveness of SHPB physical impact tests.

Key words： sandstone/quasi-sandstone split Hopkinson pressure bar (SHPB) impact compression/splitting dynamic mechanics damage mechanism
