| Abstract: | For the concrete geometry of the dispersion fuel plates,in this study,the three-dimensional representative cells are chosen to act as the research objects,which can characterize the actual deformation;the elastoplastic analysis is carried out for the thermal-mechanical coupling behaviors using the finite element method,the distribution characters of the thermal stresses at the fuel particles and matrix are demonstrated. |

| Keywords: | dispersion nuclear fuel elastoplastic three-dimensional representative volume element thermal stress thermal-mechanical coupling |
