| Abstract Scope |
Delayed hydride cracking is a primary cause of failure in nuclear materials. This study presents a computational model using phase field modelling to simulate delayed hydride cracking. The model integrates mechanical and hydrogen responses, driven by chemical and stress potential gradients. Zr-2.5%Nb alloy, commonly used in nuclear reactor pressure tubes, is employed to solve example problems. The model simulates the effect of varying hydrogen concentrations on the fracture properties of Zr-2.5%Nb alloy. The result obtained from the current model is validated with results of experimental data. This computation model shows a strong agreement with experiments, demonstrating the model's predictive capabilities. This research has significant implications for predicting and preventing catastrophic failures in nuclear environments. |
