article description
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)Bceramic 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. © (2014) Trans Tech Publications, Switzerland.
