Abstract

In many large and small scale devices metal and glass are used side-by-side. In general, metal components are coupled directly to glass components to provide extra strength. However, in certain configurations the metal-glass interface is a structural weak point. This is particularly the case when the composite metal-glass systems are subjected to impact loading. In this work the impact, and subsequent failure, process of a simply layered glass-metal-glass composite structure was investigated. The structure consisted of a core array of cylindrically shaped metal separators sandwiched between two flat sheets of soda-lime glass. High speed photography was used to capture the impact process, and the subsequent failure, of the composite. Even though significant damage was sustained at the impact point, the high speed photography showed that the initial failure point was not at the impact point.
