| Abstract Scope |
Advances in experimental characterization—most notably computed tomography (CT) scanning and optical crack surface analysis—have enabled the precise quantification of internal defect metrics such as defect volume, surface area, and spatial distribution. Integration of numerical models, including classical J2 plasticity formulations, the Gurson–Tvergaard–Needleman (GTN) model, and local-scale damage models such as the Beremin model, into finite element analysis frameworks have been established. The review synthesizes current literature on the application of these models to simulate the influence of casting defects—such as porosities, bifilms, and oxide inclusions—on the mechanical behavior of aluminum alloys. Special attention is given to the correlation between CT defect metrics and predictions of plastic deformation and crack propagation. This comprehensive review provides valuable insights for researchers and engineers aiming to optimize casting processes and improve the reliability of aluminum components in industrial applications. |
