Original abstract

The paper deals with a creation of computational model of a high porous ceramic material. This type of material has a large-scale industrial utilization. The computational model was created based on micro-CT data in the ANSYS 14.0 software using Finite Element Method. A creation of a porous ceramic struts model which respect a micro architecture is quite difficult (computer demanding and micro-CT data). The micro-CT slices are converted into a 3D model using image processing (used software STL Model Creator). The local first principle stress was analyzed because, ceramic is the brittle material. Furthermore, the influence of the thick layer around the individual struts was analyzed.

Příspěvek se zabývá vytvořením výpočtového modelu porézního keramického materiálu. Tento typ materiálu má rozsáhlé průmyslové využití. Výpočtový model byl vytvořen na základě mikro-CT dat v programu ANSYS 14.0. Vytvoření modelu, které respektují mikro architekturu je poměrně obtížné. Snímky z mikro-CT jsou převedeny do 3D modelu pomocí software STL Model Creator.Analyzovanou valičinou bylo první hlavní napětí. Dále byl analyzován vliv vrstvou kolem jednotlivých vzpěr.
