| Abstract Scope |
Material failures present significant challenges in engineering design, particularly in safety-critical applications such as nuclear reactor pressure vessels, aerospace systems, and medical devices. Existing analytical solutions for fracture, while useful, are typically limited to simple geometries and idealized crack configurations, making them difficult to apply to more complex real-world cases. The extended finite element method (XFEM) is a powerful technique for modeling mesh-independent crack propagation in complex geometries. However, an important aspect often overlooked in traditional fracture mechanics simulations is the influence of mesoscale material features on fracture propagation.
This study utilizes the XFEM implementation in the open-source MOOSE framework to examine the effect of microstructure on crack propagation in polycrystalline metallic alloys. Modeling fracture at the mesoscale, where material-specific microstructural characteristics are explicitly represented, can improve understanding of key aspects of fracture nucleation and propagation. This microstructure-informed approach can lead to more reliable fitness-for-service evaluations in complex engineering components. |
