The residual strength of glass discs after impact by high-velocity water jets has been found as a function of impact angle. An unexpected result is that under certain conditions the damage suffered is a maximum for non-normal impact. This effect is shown to be caused by radial cracks forming during the oblique impact. These cracks are not observed for normal impact and their formation is dependent upon specimen geometry. The result is of practical significance to the rain erosion situation where aircraft and missile components may suffer damage by encounters with rain drops.
