Abstract The thermomechanical response and potential cracking in nuclear fuel rods are extremely important for
nuclear safety analysis. The Pellet-Clad Mechanical Interaction (PCMI) is a significant factor for the
thermomechanical behaviors of pellet and clad. This study presents a PCMI model based on ordinary statebased peridynamic (OSB-PD) theory, which considering the heat transfer through the gap and contact heat
transfer between pellet and clad. The two-dimensional (2D) models are constructed through irregular nonuniform discretization. The pellet model includes the random variability of the critical stretch of each bond
based on normal distribution. The contact model with non-uniform discretization is proposed in… More >
