    Abstract

    The erosive damage of an infrared transparent material by a subsonic water drop impact has been numerically simulated. The important early-time pressure loading characteristics from a water drop impact are discussed, and the predicted target damage (in terms of fracture patterns) is presented for variations in material flaw size, material gain size, and impact velocity.
