Free Folding of Suspended Graphene Sheets by Random Mechanical Stimulation

Submitted by Jianliang Xiao on

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.

Which free finite element analysis software to use for this problem?

Submitted by Remi on

Hi,

 

For a personal project I'd like to find a free program that lets me see what happens when I take a beach ball and apply greater and greater weight on it.  I'm specifically interested in the deformation of the ball, and the stresses in the material.

 

Geometry&FEM connection in Mechanical APDL (ANSYS)

Hello everbody,



I'm mechanical engineer and working as FEA Engineer in GATES. I have
been using ANSYS for 5 years and I want to ask a question about new
version of ANSYS.



I use ANSYS Mechanical 12.1. I connect "geometry" and "setup" to
Mechanical APDL box in "project schematic". Then when I open Mec. APDL, I
can see the cad model (areas, lines, volumes) and FEM (nodes, elements)
but they aren't connected to each other. is there any way to connect
solid model to finite element model?





Best Regards.

Hi

I have a question regarding calculating the B-matrix which is used to create the bimaterial H-matrix in the article: "Singularities, Interfaces and Cracks in Dissimilar Anisotropic Media" by Zhigang Suo, 1989.
