Effect of irradiation swelling on the mechanical properties of unidirectional SiC/SiC composites: a numerical investigation at microstructural level

Abstract:

In order to apply SiC/SiC composites in nuclear systems, it is essential to understand the potential effects of dimensional changes induced by neutron irradiation on property degradation. A microscale model has been developed to predict the mechanical behaviour of irradiated fibre composites, including matrix cracking and interface debonding. The present work investigated the states of residual stresses and damage that may be induced by swelling mismatch between fibres and matrix, and their s...
