This report summarizes the results of a comprehensive numerical analysis of splitting-tensile and direct tension tests of plain concrete performed at strain rates between 1 and 100 on a Split Hopkinson Pressure Bar SHPB. The objective of the study was to gain some insight into failure mechanisms of concrete at strain rates associated with high intensity loadings from conventional explosives. Both an elastic and an inelastic concrete model were employed in all numerical analyses. The modes of failure predicted by the numerical analyses are consistent with those observed in experimental studies. A definite pattern between load rate and mode of failure was established.
