Liquid crystal elastomers wrinkling

Abstract When a liquid crystal elastomer layer is bonded to an elastic layer, it creates bilayer with interesting properties that can be activated by applying traction at the boundaries or optothermal stimulation. Here, we examine wrinkling responses in three-dimensional nonlinear systems containing monodomain and homogeneous isotropic incompressible hyperelastic such one thin compared other. The caused combination of mechanical forces external stimuli. To illustrate general theory, which valid for range deformations, assume nematic director uniformly aligned parallel interface between two layers, biaxial act either perpendicular director. We then perform linear stability analysis determine critical wave number stretch ratio onset wrinkling. In addition, demonstrate plate model also applicable when this much stiffer than substrate.
