Directing the Deformation Paths of Soft Metamaterials with Prescribed Asymmetric Units

By prescribing asymmetric ligaments with different arrangements in elastomeric porous membranes of pre‐twisted kagome lattices, the buckling instability is avoided, allowing for smooth and homogenous structural reconfiguration in a deterministic fashion. The stress–strain behaviors and negative Pois...

Description
Summary:By prescribing asymmetric ligaments with different arrangements in elastomeric porous membranes of pre‐twisted kagome lattices, the buckling instability is avoided, allowing for smooth and homogenous structural reconfiguration in a deterministic fashion. The stress–strain behaviors and negative Poisson's ratios can be tuned by the pre‐twisting angles.
