arXiv:2606.31921v1 Announce Type: new Abstract: Cohesive Zone Models (CZMs) are widely used to simulate interface fracture, delamination, adhesive failure, and fiber--matrix debonding in aerospace composite structures. In implicit quasi-static finite element analyses, cohesive softening may introduce negative interface tangents, solution jumps, and Newton-basin mismatch, so the previous converged state can become a poor initial guess for the next increment. This may lead to stagnation, wrong-branch convergence, or repeated step cuts. Existing remedies, including viscous regularization, path fo
The paper leverages recent advancements in neural networks to address long-standing challenges in simulating complex material behaviors, reflecting a maturation of AI applications in scientific computing.
Improving the accuracy and robustness of cohesive zone models, particularly with neural network preconditioning, enables more reliable simulation of critical composite structures, reducing design cycles and failure rates.
The application of neural networks could significantly enhance the efficiency and precision of finite element analysis for materials science, potentially shortening development timelines for aerospace and advanced materials.
