This study investigates a novel approach to combine the TPMS filler and hexa-chiral tube structures for quasi-static and dynamic loading. The TPMS structures are particularly prone as a tube filler for their excellent energy-absorbing properties, whilst the hexa-chiral lattice offers auxetic behavio ...

This paper proposes an innovative multi-material approach for introducing auxetic behaviour to syntactic foams (SFs). By carefully designing the size, shape, and orientation of the SFs, auxetic deformation behaviour was induced. Re-entrant hexagon-shaped SF elements were fabricated using expanded pe ...
