Material-aware rapid prediction of low-velocity impact damage in laminated composites via surrogate modeling

Low-velocity impact (LVI) can leave laminated composites with internal damage that is difficult to observe visually but may still degrade structural integrity. Finite-element simulation can resolve such damage fields, yet repeated case-specific analyses become costly when impact direction, ply orientation, stacking seq...

Enhancing local robustness with Hölder regularization.

Deep neural networks (DNNs) are vulnerable to small input perturbations, resulting in instability and adversarial susceptibility. While adversarial training methods such as PGD-AT and TRADES improve robustness by generating worst-case adversarial examples, they do not explicitly regulate the model's local smoothness. I...
