| 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 used to model the delayed hydride cracking. The model simulates the effect of varying hydrogen concentrations on the properties of Zr-2.5%Nb alloy. The result obtained from the current model is validated with results of experimental data. This computation model strongly agrees with the experiment, demonstrating the model's predictive capabilities. This research has significant implications for predicting and preventing catastrophic failures in nuclear environments. |
