요약Mechanical metamaterials (or mechanical meta-structures) are artificial materials that derive their extraordinary physical properties from the unique structural forms rather than constituent materials. Kirigami, the ancient paper cutting art, has recently emerged as a simple yet powerful strategy for constructing mechanical metamaterials with programmable material properties, which has found broad applications in tunable acoustic and optical structures, soft robotics, energy harvesting/saving structures, and soft electronics. Despite the recent advances, current state-of-the-art studies mainly focus on two-dimensional (2D) thin sheets-based kirigami structures with limited degrees of freedom (DoF) deformation and neglected structural thickness. The vast design space by extending the planar kirigami approach to three-dimensional (3D) bulk materials remains unexplored by releasing the constrained DoF in 2D kirigami structures. In this dissertation, a generic method of constructing 3D kirigami structures is proposed by discretizing 3D bulk materials into a number of closed-loop connected cubes in the form of different tessellated and hierarchal structures. The kinematics and kinematic bifurcation of their 3D shape transformation are studied and their potential applications in reconfigurable robotics and programmable mechanical metamaterials are explored.Chapter 2 presents a generic method of constructing 3D modular kirigami structures by dissecting the rectangular cross sectioned solid 3D prisms into 4/6/8 identical cubes. The 8-cube based 3D modular kirigami has the richest deforming features with more than one reconfiguration paths. By modeling it as an 8R-looped-linkage mechanical mechanism, the 8-cube based 3D modular kirigami structure exhibits kinematic bifurcation by branching into extra shape-changing routes at singular transfiguration states. Its kinematic bifurcations and reconfiguration kinematic have both been validated based on a transformation matrix and the singular value decomposition (SVD) method. Then, two periodic re-programmable kirigami matter separately with compact and dilute network forms are constructed, which can forwardly and inversely transform into a variety of desired surface shapes with different Gaussian curvatures.Inspired by conventional 2D hierarchical kirigami structures, Chapter 3 discusses a system of 3D modular kirigami based hierarchical structures. The hierarchical modular structures can be combinatorically designed using the bottom-up and top-down approaches. For the bottom-up approach, it can rearrange the linkage connections of different-leveled structures, combine distinct types of linkage mechanisms as structural motifs, and use level-1 structures with different number of structural components. For the top-down approach, it can change the topological geometries of structural components from cube to thick panels, polygons and prisms, and extend it to volumetric structures. Enabled by its intrinsic structural features and kinematic bifurcations, the hierarchical modular structures exhibit high structural DOFs to continuously reconfigure into varieties of 3D shapes. Despite the large number of achieved 3D shapes, thanks to the small number of structural DOFs with reconfiguration governed by simple kinematics, their transformation can be achieved in both a controllable and an untethered way driven by electrical servo-motors for actuation. Their potential applications in architectural structures, robotics, medical devices, and reconfigurable spacecraft are discussed.Beyond the hierarchical modular structures, Chapter 4 discusses a hierarchical mechanical meta-structure (HMM) with a periodic structural form based on the 3D modular kirigami inspired hierarchical unit cell. The unit cell is composed of a level-1 building block of 4 identical cubeshaped structural components and combined with level-2 building blocks through over-constrained hinge connections. The unit cell can undergo kinematic bifurcation to render a bistable deformation mode. With the independent bi-stable reconfiguration behavior, the HMM demonstrates multi-stability under pre-stretched strain. Its potential applications in load-bearing architectures, mechanical memory storage, information interaction/encryption and mechanical binary logic computation devices are also discussed.Lastly, Chapter 5 discusses extending the concept of 3D modular kirigami structure to construct mechanical metamaterials with programmable mechanical properties. Extruding the solid cube components into a thin-walled cube with two open ends makes it deform in a soft deformation mode, i.e., shearing around the extruding direction. Several categories of 1D/2D/3D mechanical metamaterials are constructed through conformably assembly ways without joining and connection between building blocks, which makes them easy to be disassembled and reassembled. The 1D/2D mechanical metamaterials demonstrate topologically programmable deformation behaviors such as structural chirality transition. The mechanical properties of the 3D metamaterials can be programmed through combinatorial designs with independent deformation modes.
