Bioinspired Materials, Designs, and Manufacturing Strategies for Advanced Impact‐Resistant Helmets
Advanced Engineering Materials, Volume 27, Issue 22, November 2025.This review explores how bioinspired materials, structures, and manufacturing strategies transform helmet design to achieve enhanced impact resistance. Drawing inspiration from nacre, porcupine quills, beetle exoskeletons, and skull architectures, it highlights advances in auxetic lattices, nanocomposites, and functionally graded foams.

International Journal for Numerical Methods in Engineering, Volume 126, Issue 18, 30 September 2025.ABSTRACT There is a variety of microstructured materials that involve voids and pores, for example, high‐porosity foams, mechanical metamaterials, or composites involving defects due to damage and cracking, respectively. Computational methods based on the fast Fourier transform (FFT) typically face convergence problems for such microstructures unless ...

A phase-field method for modeling cracks with frictional contact
, 2019 We introduce a phase-field method for continuous modeling of cracks with frictional contacts. Compared with standard discrete methods for frictional contacts, the phase-field method has two attractive features: (1) it can represent arbitrary crack ...

XFEM appliquée aux structures aéronautiques
, 2017 Dans le domaine des structures primaires aéronautiques, la tolérance aux dommages devient un critère de plus en plus dimensionnant. Basé essentiellement sur des méthodes analytiques ou modèles numériques simplifiés, la levée de conservatismes de calcul et la rapidité d’obtention de scénarios critiques deviennent limitant.
