Abstract
In this study, we develop the constitutive model to analyse the self-healing ceramic materials within the framework of FEM. The isotropic damage and self-healing constitutive model for ceramic materials can describe not only the damage process under a certain boundary condition, but also the self-healing process under arbitarary high-temperature and oxygen pressure condition. The damage process is formulated based on the fracture mechanics, while the self-healing process is formulated based on the kinetic model of self-healing time and velocity. We then apply the proposed model to analyses of alumina/SiC nanocomposites.
