Static and dynamic crushing of polymeric lattices fabricated by fused deposition modelling and selective laser sintering – an experimental investigation

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. Their stress-strain responses and crushing patterns were compared with...
