主 题:Energy absorbance Lattice structures Bio-inspiration Fused deposition modeling Lightweight design
摘 要:The increasing demand for energy absorbent structures,paired with the need for more efficient use of materials in a wide range of engineering fields,has led to an extensive range of designs in the porous forms of sandwiches,honeycomb,and *** achieve an even better performance,an ingenious solution is to learn how biological structures adjust their configurations to absorb energy without catastrophic *** this study,we have attempted to blend the shape freedom,offered by additive manufacturing techniques,with the biomimetic approach,to propose new lattice structures for energy absorbent *** this aim we have combined multiple bio-inspirational sources for the design of optimized configurations under compressive *** lattice structures are fabricated based on the designed unit cell geometries and studied using experimental and computational *** individual effect of each bio-inspired feature has been evaluated on the energy absorbance performance of the designed *** on the design parameters of the lattices,a tuning between the strength and energy absorption could be obtained,paving the way for transition within a wide range of real-life applicative scenarios.
