Kang, Jingtian published the artcileControllable bistable smart composite structures driven by liquid crystal elastomer, Formula: C17H28O8S4, the main research area is liquid crystal elastomer smart composite simulation.
In this article, we proposed a new way to achieve monostable and bistable characteristics of composite layers based on liquid crystal elastomer (LCE). A smart trilayer composite structure is fabricated using LCE and acrylic elastomer, which can have several morphologies. It keeps flat at room temperature and can deform into a monostable saddle or bistable cylinder surface in response to simple temperature changes. The reversible deformation can be controlled through two parameters including geometrical size and actuation strain. The LCE can be programmed to generate different actuation strains by different formulas during synthesis or different mech. stretches during UV radiation. The deformed morphol. for different sample sizes and actuation strain is calculated using Finite element simulation. By comparison with the exptl. results, we confirm that the phenomena can be captured through numerical simulations. Furthermore, to have a quant. understanding, we use numerical simulation to calculate the deformation of the composite structure by tuning these two parameters and give a morphol. portrait illustrating the relationship between the deformed shape and control parameters.
