Abstract Scope The intrinsic compression strength of ceramics and glasses can be difficult to determine. The specimen geometry and test fixture, if not properly designed, can result in the generation of undesirable tensile stresses that can lead to misleadingly low strength values. Since compression strength is a parameter in numerous modeling and simulation packages used to predict impact performance it is imperative that it is properly measured. A variety of ceramics and glasses were machined into a dumbbell-shaped specimen that was designed to increase the likelihood of fracture initiating in the gage section. Quasi-static experiments were performed using a screw-driven load frame while a split-Hopkinson pressure bar system was used for high-strain rate experiments. High speed imaging recorded the fracture process in all tests. This presentation will summarize the results to date on boron carbide, silicon carbide, and alumina, as well as materials such as spinel and AlON and a few glasses.
