Core Concepts
Liquid crystal polymer networks are modeled using a reduced membrane model, focusing on actuated deformations and numerical simulations.
Abstract
The content discusses the derivation of a 2D membrane model from 3D rubber elasticity, numerical simulations of LCNs/LCEs, and the prediction of equilibrium shapes. It covers the energy scaling with thickness, discretization methods, and asymptotic profiles of defects. The importance of isometric immersions in minimizing stretching energy is highlighted.
