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.
