Abstract
Biomimetic lattice structures are one of the hotspots in current new material/structural technologies, and these
lattice structures often have extraordinary mechanical properties. This work proposes a bamboo-inspired porous
lattice structure (BPLS) that consists of bamboo-inspired prismatic microstructures (BPMs) and connecting
plates. The sample of BPLS is fabricated by 3D printing, and the axial compression characteristic of BPLS is
studied through simulation analysis and experiment. The deformation mode of BPLS is very stable that has
excellent energy absorption effect. The effects of five geometric parameters on the compression performance of
the BPLS are investigated. The deformation modes of its cells are analyzed in-depth to study their compressive
behavior, and some meaningful conclusions are obtained. In addition, through reasonable parameter design,
the BPLS can realize the novel deformation modes of upper cells contraction, lower cells contraction or the
upper and lower cells contraction simultaneously and the middle cells expansion. Their deformation modes
are like budding flowers. In summary, the BPLS exhibits extraordinary mechanical properties and deformation
modes, and has broad application prospects.
