Strain-rate effects in fibre-reinforced concrete subjected to impact and impulsive loading

Abstract One of the most important properties of fibre-reinforced concrete is its considerably improved impact resistance compared to that of the unreinforced matrix. Although tests for determining the impact resistance can be tailored to suit practical situations, a more basic knowledge of the mechanical properties of the composite at the high strain-rates caused by impact would pave the way for more rational analysis and design of fibre-reinforced concrete structures subjected to impact. In this paper the tests conducted by various investigators to assess the impact resistance of fibre-reinforced concrete are reviewed, and some recent work conducted by the authors to obtain more basic material properties is presented.
