Abstract
The ablation of ultra-high-temperature ceramics (UTHCs) is a complex physicochemical process including
mechanical behavior, temperature effect, and chemical reactions. In order to realize the structural
optimization and functional design of ultra-high temperature ceramics, a coupled thermo-chemomechanical bond-based peridynamics (PD) model is proposed based on the ZrB
2 ceramics oxidation kinetics
model and coupled thermomechanical bond-based peridynamics. Compared with the traditional coupled
thermo-mechanical model, the proposed model considers the influence of chemical reaction process on the
ablation resistance of ceramic materials. In order to verify the reliability of the proposed model, the thermomechanical coupling model, damage model and oxidation kinetic model are established respectively to
investigate the applicability of the proposed model in dealing with thermo-mechanical coupling, crack
propagation, and chemical reaction, and the results show that the model is reliable. Finally, the coupled
thermo-mechanical model and coupled thermo-chemo-mechanical model are used to simulate the crack
propagation process of the plate under the thermal shock load, and the results show that the oxide layer
plays a good role in preventing heat transfer and protecting the internal materials. Based on the PD fully
coupled thermo-mechanical model, this paper innovatively introduces the oxidation kinetic model to
analyze the influence of parameter changes caused by oxide layer growth and chemical growth strain on the
thermal protection ability of ceramics. The proposed model provides an effective simulation technology for
the structural design of UTHCs.
