This project has been concerned with developing techniques for the study of liquid impact, with studying the behaviour of various infra-red transparent solids and with analytic work on hard coatings. Damage has been assessed quantitatively by measuring the residual strength after impact and plotting strength against velocity. Section 2 of this report describes an analysis of residual strength curves. The comparison between the analytic predictions and the experimental curves is good. Sections 3 and 4 describe the results of finite element analysis for the case of i Hertzian and ii uniform pressure loading of substrates with a hard coating. The protection offered by the coating is examined in terms of the elastic properties of the coating and its thickness. Author
