Investigation of the Impact Performance of Various Glass and Ceramic Systems

Abstract

This report describes our research on the impact behavior of various glass and ceramic systems. The first section describes the liquid impact technique and experiments in which high velocity liquid jets were fired at specimens over a range of velocities and the post impact (i.e. residual ) strength measured. The jet technique is velocities and the post impact (i.e. residual ) strength measured. The jet technique is a convenient method for applying an intense stress pulse and studying the dynamic response a material. If impact experiments are made over a range of velocities, it is possible to plot residual strength versus impact velocity. Such curves give the threshold velocity for damage and also show how rapidly the strength decreases for impacts above the threshold condition.
