Shape multistability in flexible tubular crystals through interactions of mobile dislocations
Andrei Zakharov, Daniel A. Beller
We study avenues to shape multistability and shape-morphing in flexible crystalline membranes of cylindrical topology, enabled by glide mobility of dislocations. Using computationa…
Modeling mechanochemical pattern formation in elastic sheets of biological matter
Andrei Zakharov, Kinjal Dasbiswas
Inspired by active shape morphing in developing tissues and biomaterials, we investigate two generic mechanochemical models where the deformations of a thin elastic sheet are drive…
Mechanochemical induction of wrinkling morphogenesis on elastic shells
Andrei Zakharov, Kinjal Dasbiswas
Morphogenetic dynamics of tissue sheets require coordinated cell shape changes regulated by global patterning of mechanical forces. Inspired by such biological phenomena, we propos…
Fiber-based shape-morphing architectures
Andrei Zakharov, Len M. Pismen, Leonid Ionov
We describe a combined experimental and theoretical investigation of shape-morphing structures assembled by actuating composite (Janus) fibers, taking into account multiple relevan…
Programmable Filaments and Textiles
A. P. Zakharov, L. M. Pismen
We analyze the various morphing structures obtained by actuating Janus filaments comprising driven and passive sectors and textiles incorporating driven and passive filaments. Tran…
Multiplicity of actuated shapes in woven fabrics with twisted Janus fibres
A. P. Zakharov, L. M. Pismen
We investigate actuation of woven fabrics including active Janus fibres with an imposed twist, which bend in variable directions upon phase transition between isotropic and nematic…
Reshaping of a Janus ring
A. P. Zakharov, L. M. Pismen
We consider reshaping of closed Janus filaments acquiring intrinsic curvature upon actuation of an active component -- a nematic elastomer elongating upon phase transition. Linear…
Active textiles with Janus fibres
A. P. Zakharov, L. M. Pismen
We describe reshaping of active textiles actuated by bending of Janus fibres comprising both active and passive components. A great variety of shapes, determined by minimising the…
Phase separation and folding in swelled nematoelastic films
A. P. Zakharov, L. M. Pismen
We explore reshaping of nematoelastic films upon imbibing an isotropic solvent under conditions when isotropic and nematic phases coexist. The structure of the interphase boundary…
Textures and shapes in nematic elastomers under the action of dopant concentration gradients
A. P. Zakharov, L. M. Pismen
We explore a novel strategy of patterning nematic elastomers that does not require inscribing the texture directly. It is based on varying the dopant concentration that, beside shi…
Flexible helical yarn swimmers
A. P. Zakharov, A. M. Leshansky, L. M. Pismen
We investigate the motion of a flexible Stokesean flagellar swimmer realised as a yarn made of two intertwined elastomer fibres, one active, that can reversibly change its length i…
Nemato-elastic crawlers
A. P. Zakharov, L. M. Pismen
A propagating "beam" triggering a local phase transition in a nematic elastomer sets it into a crawling motion, which may morph due to buckling. We consider the motion of the vario…
Reshaping nemato-elastic sheets
A. P. Zakharov, L. M. Pismen
We consider three-dimensional reshaping of thin nemato-elastic sheets containing half-charged defects upon nematic-isotropic transition. Gaussian curvature, that can be evaluated a…
