Implication

This analysis reveals auxetic unit cell geometry and wall thickness influence energy absorption in sandwich composites, suggesting design improvements.

Key Points

The arrowhead core showed the highest absorbed energy of 87.30 J in low-velocity impact tests, enhancing durability.
Thinner-walled auxetic designs yielded higher peak forces, indicating trade-offs between strength and brittleness.
Testing included four auxetic geometries and varying wall thicknesses to optimize energy absorption performance.
Finite element simulations aligned well with experimental data, validating the structural response of the sandwich panels.
