Abstract

Custom folded 3-dimensional plate lattices are modularly assembled to form structures with single and double curvature for use in structural engineering and robotics applications. The plate lattice structural corrugation uses a building block strategy and incorporates custom modified unit cells based on a Kirigami Expanded Miura pattern. This transformation involves expanding the top and bottom zig-zag crease lines into facets and orienting them in space. The structure of these lattices allows for the design of anisotropies in their flexural stiffness by alternating between the Maxwell criterion on bending-dominated and stretch dominated cells. These anisotropies can have value differences of up to 24 times with the same geometry, making them ideal for robotic morphing applications.
