Analysis of dispersion-type nuclear fuel using Eshelby's solution

Eshelby's solution was used for the analysis of dispersion-type nuclear fuel, considering the thermal field and irradiation-induced swellings. The impact of particle shape and irradiation-induced swellings on stress field was discussed. The maximum of the first principal stress and Von Mises equivalent stress can be found on the interface between the matrix and the particle, whose value is related with the particle shape and other factors. And the irradiation-induced swellings enhance the first principal stress and Von Mises equivalent stress very strongly.(authors)
