摘要
Using the concept of meso-mechanics, microscopic thermal stress and strain fields of the dispersion nuclear fuel plates are studied. With the assumption that the microstructures of fuel plates are periodic along the length and width directions, the corresponding three-dimensional Representative Volume Elements are developed, and the effects of the microstructures on the thermal-elastoplastic behaviors are investigated numerically. It is concluded that the microstructures of fuel plates can remarkably affect their mechanical properties. This study lays a foundation for optimal design of dispersion nuclear fuel elements.
