Impact loading of laminated composites ZrO$_2$/Ti and ZrO$_2$/Al with non-rigid interfaces

The article presents the results of studying the impact response of ceramic-metal composites ZrO$_2$/Ti and ZrO$_2$/Al with non-rigid fixing of layers. It is shown that, as the energy dissipates from layer to layer, there takes place an increase in the dispersion of the structure of metal foils and ceramic plates. The ZrO$_2$/Ti ceramic-metal composites have a higher impact strength, while the impact strength of layered ZrO$_2$/Al composites differs from the impact strength of monolithic ceramics only scarcely. It was shown that, regardless of the distance between the ceramic plates and the point of impact, their destruction occurs with the transformation of the ZrO$_2$ tetragonal modification into the monoclinic one.
