The simulation employs a non-penetrating impact model with a 7.3 × 7.3 × 5.5 nm 3 iron cube as the projectile, assessing molecule-ballistic performance in a single-layer fabric structure (including all 400 crossings). Normalized virial stress maps illustrate the response of the three weaves to the impact of the iron slab at pressures of 0.3, 0.6, and 0.9 GPa. Stress concentration is observed particularly at strands neighboring the impact centre. As pressure increases, impact-induced chain sliding propagates from the impact centre to the far-field region of the weave, without reaching the network boundaries. The plain weave encounters substantially greater resistance while moving through the strands. The mixed weave, possessing a moderate number of entanglements, exhibits mechanical behaviour resembling that of the plain weave at low pressure but akin to the basket weave at high pressure.
