Summary:

Multilayer materials consisting of ceramic and glass/epoxy with a rubber interlayer have been subjected to a high strain rate compression using a split-Hopkinson Pressure Bar (SHPB). The feasibility of modeling stress wave propagation in complex multilayer materials has been demonstrated. It has been shown that the effects of lateral confinement of a normally low-modulus interlayer material can significantly affect the response to wave propagation. Numerical modeling clearly shows that severe stress inhomogeneities and discontinuities exist, and theses may have serious consequences for the mechanical and other properties. The one-dimensional stress state usually assumed for conventional SHPB testing is therefore inapplicable, and both numberical and experimental results have to be coupled for a complete understanding of the wave propagation characteristics. In this study, both methods were used, and the stress states inside the components were presented.
