Particle Impact Damage in Ceramics

Abstract

The objective of this research is to understand and model the deformation and fracture response of materials exposed to water drop collisions. Due to the inherent complexity of the erosive response of materials exposed to a multiple water drop environment, this investigation concentrated on a very idealized water drop impact condition: the normal impact of a spherical water drop on a plane surface. The development of an experimental facility is described for producing spherical water drop impacts on materials at both subsonic and supersonic impact velocities. A reproducible, controlled, and well- characterized impact condition is necessary if an accurate assessment of the material's response is to be established.
