Transient FEM Modeling of Strain-Induced Self-Rolled-Up Nanotube Formation Process
Award year: 2012-2013
This project aims to use transient finite element method (FEM) to model the rolling process of strain induced rolled-up micro and nanostructures with various geometry, physical properties, and functionalities. Experimental verification will be carried out in tandem to provide critical feedback to the modeling boundary conditions and assumption. High-performance computing power is necessary when moving boundary conditions has to be used for the modeling of the realistic experimental process. This work will provide guidance to the design and assemble of these rolled-up nanostructures in a 3D origami fashion into systems that can actively adapt to environmental changes in heat, optical radiation, as well as mechanical actuation.
