The predictive capabilities of the finite element approach were assessed by comparing simulation outputs with experimental results, including load-displacement trends, damage initiation points, and delamination evolution. This comparison validated the effectiveness of the self-healing interleaves and highlighted the strengths and limitations of the adopted numerical framework. The simulations not only reproduced key damage characteristics but also provided a deeper understanding of failure mechanisms in the modified laminates. This modeling strategy contributes to the broader goal of developing high-fidelity virtual testing tools for complex, multifunctional composite structures used in aerospace and related industries.
