Proposed auxetic cluster designs for lightweight structural beams with improved load bearing capacity

[Display omitted] •Deflection behaviour of existing auxetic re-entrant beams compared with traditional beam designs.•Overlooked factors of placement and orientation of auxetic clusters utilized for enhancement.•Two new improved auxetic beam designs proposed with minimal deflection and 64% reduction...
