UHP(FR)C under impact loading

This paper describes the comparison between compressive behaviour of a commercial Ultra High-Performance (Fibre-Reinforced) Concrete, having 3% content of high carbon straight steel fibres, and its matrix. A special device named 3D-Modified Hopkinson Bar (3D-MHB) installed in the DynaMat SUPSI Laboratory was used to test cylindrical specimens with 30 mm diameter and height/diameter ratios of 1, 1.5 and 2. Experimental results were compared to those obtained numerically using the DAMP explicit material model, which can accurately represent multiple dynamic scenarios in structural analysis.
