Abstract To enhance the mechanical properties while keeping controlled auxetic performance, a novel circular reinforced re-entrant arched honeycomb (CRRAH) structure is developed. CRRAH specimens were additively manufactured, and quasi-static compression tests conducted to evaluate their performance. Results demonstrate that superior performance presented by comparing conventional structures, including remarkable 208% increase in specific energy absorption (SEA). The finite element model, validated against experimental results, was further used explore deformation mechanism of structures with varying thickness ratios (γ). indicated integrating rib within cells effectively restricts continuous rotational stretching inclined ligaments, resulting two-stage collapse process. This significantly enhances stability capacity. Moreover, adjusting ratio γ shifts mode from localized shear band formation uniform global slight lateral expansion. dependence indentation resistance on explored underlying revealed. These findings provide valuable insights into design advanced combining improved crashworthiness effects.
