Abstract

• Three novel auxetic structures based on anti-tri chiral lattice were proposed. • Experimental, numerical, and metamodeling investigation of EA. • Superior EA and NPR of MATC1 structure was observed. • Robustness of RF in predicting experiment outcomes was demonstrated. Considering the advanced properties of meta-structures in absorbing energy and high crashworthiness performance, in this work three novel auxetic-lattice structures are proposed and developed based on anti-tri chiral structure by applying the element transformation approach. The novel auxetics were made of polylactic acid plus (PLA+) and additively manufactured by fused deposition modelling. The presented designs were numerically simulated…
