Numerical study of the influences of pressure confinement on high-speed impact tests of dynamic material properties of concrete

•Pressured fluid influences the testing results of modified SHPB test system.•Strain rate sensitivity of concrete decreases with the increment of confinement.•An empirical relation is proposed to describe DIF of confined concrete. Although tests of Modified Split-Hopkinson Pressure Bar (MSHPB) syste...
