  • Static and dynamic crushing of polymeric lattices fabricated by fused

    Lightweight polymeric lattices, which display good energy absorption characteristics during crushing, are increasingly employed in impact protection applications. Lattices based on an octet, rhombic dodecahedron (RD) and a novel hybrid structure (HS), were fabricated by Selective Laser Sintering (SLS), and their dynamic responses were investigated via a drop-weight tester.

  • Experimental and numerical investigation on in-plane impact behaviour

    When subjected to high-speed impact such as v m = 25 or 50 m/s, impact performance in terms of crushing force efficiency and cushion factor benefits from the increase of r/R. Although increasing r/R from 0.04 to 0.2 can dramatically decrease Poisson’s ratio from 0.07 to − 0.63, structural Poisson’s ratio is still highly controlled by the crushing velocity.
