Discontinuous metric programming in liquid crystalline elastomers
Tayler S. Hebner, Riley G. A. Bowman, Daniel Duffy +6
Liquid crystalline elastomers (LCEs) are shape-changing materials that exhibit large deformations in response to applied stimuli. Local control of the orientation of LCEs spatially…
Metric mechanics with non-trivial topology: actuating irises, cylinders and evertors
D. Duffy, M. Javed, M. K. Abdelrahman +3
Liquid crystal elastomers contract along their director on heating and recover on cooling, offering great potential as actuators and artificial muscles. If a flat sheet is programm…
Interfacial metric mechanics: stitching patterns of shape change in active sheets
Fan Feng, Daniel Duffy, Mark Warner +1
A flat sheet programmed with a planar pattern of spontaneous shape change will morph into a curved surface. Such metric mechanics is seen in growing biological sheets, and may be e…
Shape programming lines of concentrated Gaussian curvature
D. Duffy, L. Cmok, J. S. Biggins +7
Liquid crystal elastomers (LCEs) can undergo large reversible contractions along their nematic director upon heating or illumination. A spatially patterned director within a flat L…
Evolving, complex topography from combining centers of Gaussian curvature
Fan Feng, John S. Biggins, Mark Warner
Liquid crystal elastomers and glasses can have significant shape change determined by their director patterns. Cones deformed from circular director patterns have non-trivial Gauss…
Inflationary routes to Gaussian curved topography
Emmanuel Siéfert, Mark Warner
Gaussian-curved shapes are obtained by inflating initially flat systems made of two superimposed strong and light thermoplastic impregnated fabric sheets heat-sealed together along…
