Highlights A hybrid TPMS method is proposed to develop a new TPMS structure. Hybrid TPMS structures have better energy absorption and load-bearing capability than basal TPMS structures. The crushing behavior of hybrid TPMS structures is more effective compared with the square honeycomb. The effect of the structure factor and wall thickness is significant on the crashworthiness of hybrid TPMS structure.
Abstract A hybrid triply periodic minimal surface (TPMS) method is proposed by the implicit mathematical equation to develop a new TPMS structure. Mechanical properties of the basal TPMS structures and the hybrid TPMS structure subjected to axial crushing load are experimentally and numerically investigated. Results show that the specific energy absorption of hybrid additive and subtractive TPMS structures is up to 97.2 % and 82.4 % enhancement compared to the basal Schwarz Primitive structure, and the Undulation of load-carrying capacity of hybrid additive and subtractive TPMS structure is 60.1 % and 33.3 % lower than that of the basal Schoen IWP structure. The effect of topological shape and material distribution on mechanical properties of hybrid TPMS structures are further numerically investigated, and structural factor and wall thickness have significant influence on crashworthiness. Furthermore, the crushing behavior of hybrid additive TPMS and square honeycomb subjected to in-plane and out-of-plane impact loads are investigated, and the hybrid additive TPMS structure shows significant crashworthiness advantage in in-plane crushing condition. Furthermore, the multi-objective optimization is carried out to obtain the optimal crushing performance of the hybrid additive TPMS structure. The hybrid design can provide a good guidance for the research on crashworthiness of the TPMS structures.
