Paper Abstract

Liquid crystal elastomers combine both liquid crystals and polymers, which gives rise to many fascinating properties, such as unparalleled elastic anisotropy, photo-mechanics and flexoelectric behavior. The potential applications for these materials widely range from wings for micro-air vehicles to reversible adhesion skins for mobile climbing robots. However, significant challenges remain to understand the rich range of microstructure evolution exibited by these materials. This paper presents a model for domain structure evolution within the Ginzburg-Landau framework. The free energy consists of two parts: the distortion energy introduced by Ericksen [1] and a Landau energy. The finite element method has been implemented to solve the governing equations developed. Numerical examples are given to demonstrate the microstructure evolution.
