Originální abstrakt

Highly porous brittle materials, especially ceramic foams, were studied. These materials have broad range of usage mainly in engineering practice and their application is connected above all with their unique properties, mainly low relative weight connected with large specific surface area. The tensile test of brittle, highly porous materials is rather complicated from the point of view of the realization itself, also the economical point of view as well. This is one of driving forces to create calculation models respecting highly porous structure. Commercially available ceramic foam Vukopor was investigated. Micro Computer Tomography has been used to obtaining valid data of ceramic foam structure. The aim of this paper was creation of computational model and using this model performs a comparison of struts different type under mechanical loading. The finite element method was used for calculations. The material properties of ceramic foam were determined experimentally.
