| Abstract Scope |
This work focuses on the propagation of cracks from the matrix into the tristructural isotropic (TRISO) particles. Because particle failure caused by external cracking is a unique failure mechanism for TRISO particles embedded in a SiC matrix, a better understanding of the behavior is useful. The simulations in this work are of a smooth OPyC-SiC interface similar to those common for advanced gas reactor (AGR) particles, along with a lumpy interface observed on the particles used in experiments of fully ceramic microencapsulated (FCM) compacts in which matrix cracks appear to have propagated into the particles. The shape of the interface, the SiC stress state, and the strength of the interface were the parameters considered in this work. |
