Is anyone here doing simulation on Carbon Nanotubes

Dear All,

I am new to simulations of carbon nanotubes, especially in their mechanical properties. My supposed tools are ab initio codes or md codes. I am looking for some references. Can someone introduce some classical papers or leading experts in this field.

Thanks.

Problems with FEAP compilations in Visual Studio 2008

research

I have a problem when a try to compile FEAP with visual studio 2008. The error is the next:

error #6633: The type of the actual arguments differs from the type of the dummy arguments.

I have tryed to compile several times but the error is the same.

I do not know if I have configure properly my visual studio or if it is a problem with mi FEAP.

Thank you very much.

crack-front coordinate system

mesh crack

Hi all,

I am currently working on Virtual crack closure technique. I met some problems with the local crack-front coordinate system. I wonder if i can find a detailed explanation on the coding of the local crack-front coordinate sytem.

Thanks a lot

modelling a crack in a structure, using Ansys Workbench v11.0

Submitted by Jessica Papasidero on Thu, 06/04/2009 - 09:47

hello,

I am using Ansys Workbench v11.0 to study the fracture of a structure.

I would like to add a crack in my structure, but I don' really know how to do it, since I don't have much experience of numerical simulation (actually, this is my first one in rupture mechanics).

So far, I have tried to design the crack with the Ansys Design Modeler (I have cut my piece, so that one part of it has the shape of the crack I want to study). But now, I can't manage to mesh it with Ansys Simulation.

Weak form

During the study of FEM, I found the term "weak form" of differential equation, which is the integral form of a differential equation along with the boundary conditions for a boundary value problem. Now my question is that why the term "weak" has been used.
