Reconfigurable wrinkles of a patterned liquid crystal network coating activated by polarized light
A geometrically nonlinear model is developed to explore photo-induced wrinkling of a patterned liquid crystal network (LCN) coating consisting of striped domains with orthogonal director alignments. The inhomogeneous coating is replaced by an equivalent homogeneous plate with distributed eigenstrains, and the large deflections activated by linearly polarized UV light are solved numerically via a kinetic approach. It is found that substantially different wrinkling modes can be formed when the intensity and polarization direction of the light as well as the width of the domains are changed. The results demonstrate a contactless way to create reconfigurable surface topographies.
期刊介绍：
The International Journal of Non-Linear Mechanics provides a specific medium for dissemination of high-quality research results in the various areas of theoretical, applied, and experimental mechanics of solids, fluids, structures, and systems where the phenomena are inherently non-linear.
The journal brings together original results in non-linear problems in elasticity, plasticity, dynamics, vibrations, wave-propagation, rheology, fluid-structure interaction systems, stability, biomechanics, micro- and nano-structures, materials, metamaterials, and in other diverse areas.
Papers may be analytical, computational or experimental in nature. Treatments of non-linear differential equations wherein solutions and properties of solutions are emphasized but physical aspects are not adequately relevant, will not be considered for possible publication. Both deterministic and stochastic approaches are fostered. Contributions pertaining to both established and emerging fields are encouraged.
