Numerical Analysis of Dynamic Direct Tension and Direct Compression Tests

Abstract

This report summarizes the results of a comprehensive numerical analysis of direct tension and direct compression tests of plain concrete performed at strain rates between 1 and 10 to the 2nd power on a Split Hopkinson Pressure Bar (SHPB). The objective of this study was to investigate failure mechanisms in plain concrete specimens at high strain rates. Both an elastic and inelastic concrete material model were employed in all numerical analyses. The modes of failure predicted by the numerical analyses are consistent with those observed in experimental studies. In all instances, the mode of failure was significantly influenced by the rate of loading.
