ABSTRACT：
A stretchable form of single-crystal silicon was produced by a research group in UIUC and reported in Science Journal early this year. In this system, a wavy type of Si film was formed on elastomeric substrates. The wavelength and amplitude of wavy structures was predicted by a 2D theoretical model, in which the infinite assumption is adopted and the tangential traction along the interface is assumed to be zero in order to have an analytical solution. However, the observed results showed that the boundary effects play a role in the buckling and post-buckling behavior of the system. In this work, a numerical investigation is conducted. A finite element model of the system is developed and used to predict the buckling patterns of the system and the traits of a wavy Si structure in the post-bucking state. Interesting results are observed from the simulation.
Our activities in industrial applications and research work, as well as the computing facilities and organization setup will be also introduced and reviewed in this talk.
