Investigation of the dynamic behaviour ceramic matrix composites obtained by additive technologies
Additive technologies open up new possibilities for creating materials with controlled structural features including ceramic composites. Such composites have good strength properties, fracture toughness and toughness. But not all properties are studied well. In order to predict the mechanical behavi...

| 520 | 3 | |a Additive technologies open up new possibilities for creating materials with controlled structural features including ceramic composites. Such composites have good strength properties, fracture toughness and toughness. But not all properties are studied well. In order to predict the mechanical behavior of transformation-hardened ceramic composites with a controlled structure under dynamic loads, it is convenient to use methods of numerical analysis.The aim of this work was to investigate the influence of loading speed on microstructure evolution of ZTA nanocomposites obtained by additive tecnology of fused deposition modeling. Within the framework of the study physical and mathematical model that is used in computational mechanics of materials is developed. In the paper is shown the influence of the loading rate on the strain rate in the region of the shock transition for materials based on Al2O3 - 20%ZrO2 system. The research shows nonlinear effects under intense dynamic loads in the shown composite materials are bound up with either the processes of selforganisation of deformation modes at the mesoscopic level or the occurrence of martensitic phase transformations in matrix volumes adjacent to the strengthening particles. | |
