Simulation of Thermal and Mechanical Response of (Zr,W)B2 Ceramic after Oxidation

This study relates to a micromechanics based finite element model of the effect of oxidation on heat transfer and mechanical behavior of a (Zr,W)B2 ceramic at high temperature. An adaptive remeshing technique is employed in both heat transfer and thermal stress analysis models. A global-local modeli...

Zusammenfassung:This study relates to a micromechanics based finite element model of the effect of oxidation on heat transfer and mechanical behavior of a (Zr,W)B2 ceramic at high temperature. An adaptive remeshing technique is employed in both heat transfer and thermal stress analysis models. A global-local modeling technique is used to combine finite elements with infinite elements for thermal stress analysis. Temperature and thermal stress distributions in the ceramic and the oxides are presented.
