Dynamic direct compression tests of plain concrete specimens were cond
ucted on a split-Hopkinson pressure bar (SHPB) to investigate the effe
cts of increasing strain rate on the compressive strength of concrete.
A comprehensive finite element method study was performed on the SHPB
experiments. Both linear and nonlinear analyses were conducted. The r
esults of the numerical analyses disclose the dynamic states of stress
in the concrete specimen prior to failure as well as the modes of fai
lure.
