In this paper we attempt to answer two questions on graphene from a mechanic’s viewpoint: why does this one-atom-thick monolayer have finite bending stiffness to ensure its stability? and what is its wrinkle mechanism? As for the first question, it is found that the repulsive residual internal moment in the bond angle can lead to a nonzero bending stiffness, which makes the graphene flat. Together with long-range attraction among atoms, such as van der Waals forces, a graphene prefers to have a self-buckling wrinkled configuration with many waves.

Computational Modeling & Analytics (Assistant/Associate Professor)

Combining
soft active hydrogels with hard passive polymers gives rise to all-polymer
composites. The hydrogel is sensitive to external stimuli while the passive
polymer is inert. Utilizing the different behaviors of two materials subject to
environmental variation, for example temperature, results in self-folding soft
machines. We report our efforts to model the programmable deformation of
self-folding structures with temperature-sensitive hydrogels. The self-folding
structures are realized either by constructing a bilayer structure or by
incorporating hydrogels as hinges. The methodology and the results may aid the

In this Paper, the nonlinear free and force vibration of a single-walled carbon nanotube (SWCNT) with simply supported ends is 

investigated based on von Karman’s geometric nonlinearity. The SWCNT described as an individual shell and the Donnell’s 

equations of cylindrical shells are used to obtain the governing equations. The Galerkin's procedure is used to discretized partial

It is very important to visualize molecular dynamics (MD) trajectories since there are many aspects of MD simulations which are difficult to identify without a proper visualization tool. Improper bounday condition in MD is one of such examples. I use Visual Molecular Dynamics (VMD) to visualize my MD simulations. Some of my movies, created using VMD, are shown below.
