Wave and Fracture Phenomena in Impacted Ceramics.

Abstract

An optical measuring technique in combination with high speed photography is provided to solve the problem of this contract, the investigation of wave and fracture phenomena in opaque ceramic materials. Surface disturbances caused by these mechanical events will deflect reflected light from its ordinary direction and thus give rise for shadow patterns which can be photographed. Specimens with the dimensions 100mm by 10mm shall be impacted on one of the smaller surfaces by a projectile in order to generate these events. In parallel to this work it has also been intended to prepare specimens of alumina, for it is believed that with this material results can be obtained easier than with boroncarbide.
