4D Printing Self-Morphing Structures. [PDF]

Materials (Basel), 2019
The main objective of this paper is to introduce complex structures with self-bending/morphing/rolling features fabricated by 4D printing technology, and replicate their thermo-mechanical behaviors using a simple computational tool. Fused deposition modeling (FDM) is implemented to fabricate adaptive composite structures with performance-driven ...

Topology Morphing Lattice Structures

ASME 2021 Conference on Smart Materials, Adaptive Structures and Intelligent Systems, 2021
Abstract Planar cellular lattice structures subject to axial compression may undergo elastic bending or buckling of the unit cells. If sufficient compression is applied, the columns of adjacent cells make contact. This changes the topology of the lattice by establishing new load paths.
