Abstract

The dynamic response of ceramic materials has been the subject of intense research in the past decade. In this paper, we succinctly describe a plate impact experiment of a star-shaped flyer on a square Al2O3 specimen, and report microscopy observations which reveal the origin of inelasticity. The experimental method has been extensively described by Raiser et al. (1991), where measured velocity profiles are reported. A full account of the microscopy studies, as well as of extensive numerical analyses demonstrating the viability of the micromechanisms postulated here will be given elsewhere.
