Liquid Impact Erosion Mechanisms in Transparent Materials.

Abstract

A STUDY HAS BEEN MADE OF DAMAGE MECHANISMS CAUSED BY LIQUID DROP IMPACT ON VARIOUS INFRA-RED TRANSPARENT SOLIDS. Techniques are described for producing liquid jets which simulate the damage produced by impact with spherical drops. Advantages of this approach are the simplicity of the experimentation, the low construction cost and the broad range of drop size and velocity which can be covered. A hydraulic strength measuring apparatus for brittle materials is described which allows 'residual strengths' to be measured. Materials examined in this report include silicon nitride, zinc sulphide and zinc selenide. (Author)
