Abstract Scope |
Metamaterials are a novel class of engineering materials intended to exhibit unmatched properties, not present in conventional materials. This research presents an experimental and numerical study of three novel elastic unit cells with interlocking mechanisms subjected to uniaxial quasistatic compression loading. A finite element model is used to determine the dimensions of the elastic unit cell samples for the experiment. The elastic mechanical metamaterial unit cells were fabricated from thermoplastic polyurethane material (TPU) using a commercial 3D-printer. The results of the uniaxial compression test for all unit cells are collected and evaluated. Different distinctive deformation behavior was observed in proposed elastic unit cells, having two regions within the elastic limit, where soft stiffness transitions into a hard stiffness material, thus showing bilinear stiffness behavior. The proposed elastic unit cells presented here may become fundamental unit cell in articulated structures used in a broad range of engineering applications. |
