Liquid Impact Erosion Mechanisms in Transparent Materials.

Abstract

A study has been made of damage mechanisms caused by liquid drop impact on various infrared transparent solids. Techniques are described for producing liquid jets which simulate the damage produced by impact with spherical drops. Fracture damage to specimens is studied by measuring the post-impact 'residual strength' using a specially developed hydraulic loading test. Damage produced in ZnS by indentation and by impact is discussed in detail. Finally, residual strength curves produced by multiple jet impact are presented; there is a good correlation between experimental data and our theoretical analysis of the process. (Author)
