One of the most significant factors in molecular dynamic simulatin is to choose the proper potential. Recently, I did some searching jobs on Vanadium (V) potential and finally decided which potential I am going to use. Here is a simple summary:
A brief introduction of EAM, F-S and MEAM potentials for BCC transition metals
How can we perform first structural and then thermal analysis in ANSYS (version 12) ? All the examples show the sequence the other way. I can't go for Direct coupled method as the materials are elastic-plastic (plasticity is not supported by direct coupling elements).
We are interested in making contact with self-motivated candidates with significant experience in multiscale simulation, if possible with a Physics or Mathematics background for projects involving the simulation of multiscale fracture. Researchers with experience in ab initio models are particularly encouraged to make contact.
Please contact stephane dot bordas at gmail dot COM for more detail.

Hi,
I'm a fresher in abaqus. Now I'm trying to simulate the damage of brittle kind of materials, like concrete with abaqus on mesoscale. But there are some problems now...
The random meso-structure has already been generated by matlab, but I don't know how to import the information of the geometry which are some coordinates? I find the file formats which could be read by abaqus, like Autocad .dxf,.step...but I'm not sure how to do it exactly since geometry information are in terms of coodinates in matlab.
Summary:
I am thinking of informally conducting a specific case-study concerning the FEA solvers. The reference problem is a very simple but typical problem from stress analysis, leading of course to the linear systems: Ax = b and Ax = Lx.
I seek advice as to what software libraries currently available in the public domain would be best to use---the ones that would be fastest in terms of execution time for the reference problem.
Dear all,
I have read the paper titled Haversian cortical bone model with many radial microcraks: An elastic analytic solution. My problems and the paper are attached.I hope you can see the problems and the corresponding paper. Thanks for your help.
Sincerely yours,
Xu Wang
A postdoctoral fellowship is available in the Duke Computational Mechanics Laboratory, beginning in September of 2010 (with flexibility on timing). Funding for the fellowship concerns research in the simulation of dynamic fracture of polycarbonate. The ideal candidate will have experience in some combination of the following areas (in no particular order of importance):
I read this article today, perhaps other beginners like me can also get some benefit from this:
Title: Overview of constitutive laws, kinematics, homogenization and multiscale methods in crystal plasticity finite-element modeling: Theory, experiments, applications.
