Abstract The reactor pressure vessels (RPV), a typical kind of axisymmetric structures, usually serve under high
temperature and pressure conditions. The numerical analysis of the mechanical behaviors of these
structures plays a dominant role for their structural design, advanced manufacture and safety assessment
in practical engineering applications[1-2]. However, the extremely conditions bring great challenges for the
numerical analysis of structures undergo ablation, plastic, damage and even fracture during an accident[3].
Based on the superior performance of peridynamics model in predicting fracture behaviors [4-7], a coupled
axisymmetric non-ordinary state-based peridynamics (CA-NOSB-PD) model is proposed in this work to
predict the ablation, plastic… More >
