Method & Evidence

AimCan nature-inspired open lattice structures be designed to significantly enhance plateau stress and specific energy absorption compared to existing lattice and honeycomb designs under quasi-static and dynamic loading?

MethodSimulation and Experimental Validation

ProcedureMultiple variations of a novel open flower lattice structure (NINOFL) were designed, fabricated using additive manufacturing (powder bed fusion with SS316L), and characterized. Mechanical performance was evaluated through quasi-static compression tests and dynamic compression tests using a Split Hopkinson Pressure Bar. Finite Element Analysis (FEA) simulations were conducted to understand deformation mechanisms and validate experimental results. Performance was benchmarked against honeycomb and merged tessellated open-type lattice structures.
