Mechanical performance of 4D-printed honeycombs with various Poisson’s ratios under quasi-static and low-velocity compression

Four-dimensional (4D) printing provides a promising route for prototyping reusable energy-absorbing metamaterials that can recover their geometry after large deformation. However, the cyclic performance of 4D-printed shape-memory honeycombs remains governed by topology, loading d...
