Energy Balance in Instrumented Impact Tests on Plain Concrete Beams
Abstract Impact tests were carried out on plain concrete beams, 100 mm × 125 mm in cross-section and 1400 mm long, using an instrumented drop weight impact machine. The machine, capable of dropping a 345 kg mass through heights of up to 2.3 m, had strain gauges attached to the striking end of the hammer, and also to one of the support anvils. In addition, in order to record the beam response during the impact, three accelerometers were mounted along the length of the beam. Normal strength and high strength concretes were tested. For three different drop heights, the energy lost by the hammer was compared to the energy gained by the beam in various forms. It was found that up to the peak load, the energy gained by the beam was only a small percentage of the energy lost by the hammer. However, by the end of the impact event, most of the energy lost by the hammer could be accounted for.
