Mechanical metamaterials (MMMs) have become a research hotspot in the application of aerospace
energy automobile
manufacturing
and military due to their light weight
high strength
and high energy absorption. Selective laser melting (SLM) additive manufacturing can produce complex microstructure with high precision and resolution
thus being suitable to fabricate complex MMMs. In this study
a design scheme of three-dimensional (3D) MMMs models based on a“ double V” configuration honeycomb topology was proposed
which were subsequently printed by SLM. Through the combination of theoretical calculation
simulation
and experiments
the influences of various structural parameters on the compression mechanical response of the “double V” configuration honeycomb MMMs were investigated. The findings provide an approach to manually tailor the negative Poisson's ratio of MMMs.
