Laser-based additively manufactured bio-inspired crashworthy structure: Energy absorption and collapse behaviour under static and dynamic loadings

• A novel lattice structure inspired from the beetle's front wing and the arrangement pattern of honeycomb cells is proposed. • The deformation mechanisms of the bio-inspired lattice structure under static and dynamic loading are unveiled. • The specific energy absorption of the bio-inspired lattice structure exhibits certain sensitiveness to the strain rate. • Numerical simulations using Johnson-Cook constitutive model of heat-treated AlSi10Mg...
