Detecting delamination in FRP retrofitted concrete structures using nonlinear ultrasonics

Fibre reinforced polymers (FRPs) are increasingly used to retrofit concrete structures due to their many desirable properties. Researchers from the University of Exeter report on a series of experiments that apply nonlinear elastic wave spectroscopy to concrete beams strengthened with externally bonded FRP, in order to detect the onset of failure.
