An exact dimension-reduced dynamic theory for developable surfaces and curve-fold origami
Zhixuan Wen, Sheng Mao, Huiling Duan +1
Curve-fold origami, composed of developable panels joined along a curved crease, exhibits rich dynamic behaviors relevant to metamaterials and soft robotic systems. Despite multipl…
A continuum mechanics approach for the deformation of non-Euclidean origami generated by piecewise constant nematic director fields
Linjuan Wang, Fan Feng
We merge classical origami concepts with active actuation by designing origami patterns whose panels undergo prescribed metric changes. These metric changes render the system non-E…
Beyond mechanochromism: Programmable multimodal actuation in cholesteric liquid crystal elastomer hollow fibers
Jiazhe Ma, John S. Biggins, Fan Feng +1
Cholesteric liquid crystal elastomers (CLCEs) change color under strain, offering attractive prospects for smart textiles, soft robotics, and photonic devices. However, the helical…
Geometry and Mechanics of Non-Euclidean Curved-Crease Origami
Zhixuan Wen, Tian Yu, Fan Feng
Recently there have been extensive theoretical, numerical and experimental works on curved-fold origami. However, we notice that a unified and complete geometric framework for desc…
A generalized geometric mechanics theory for multi-curve-fold origami: vertex constrained universal configurations
Zhixuan Wen, Pengyu Lv, Fan Feng +1
Folding paper along curves leads to spatial structures that have curved surfaces meeting at spatial creases, defined as curve-fold origami. In this work, we provide an Eulerian fra…
