Graphene edges, analogous to the structure of nanotubes, can significantly influence the overall electronic and magnetic properties of graphene nanostructures, and thus have become important issues in graphene research, especially for electronic applications. In this recent paper published on PRL, we reported that the free folding of suspended graphene sheets by random mechanical stimulation has preferred folding directions.

Phanish Suryanarayana, from the California Institute of Technology, is the 2010 Melosh Medalist for the Best Student Paper in Finite Element Analysis.  Phanish won for his paper titled "Non-periodic Finite-Element and Mesh-Free Formulation of Kohn-Sham Density Functional Theory".  He presented the paper on Friday, April 30, 2010, on the campus of Duke University.

Theory of dielectric elastomers capable of giant deformation of actuation

Xuanhe Zhao, Zhigang Suo

Physical Review Letters, 104, 178302 (2010)

Hey.

I want to model an anchored sheet pile wall placed in a completly saturated clay material, where

the excavation steps on the left side of the wall have to be taken into account.

I am using the keyword in ABAQUS "*Model change, Remove" to remove my elements, so I can

simulate the excavation steps. Unfortunately, my pore pressures seem stranges in the

model when I am using this keyword.
