I am going to do MD simulation on polymer nanocomposites in order to measure the mechanical properties and density of the interphase between fiber and matrix. my filler is platetlet. I read some paper in which similiar work has been done some of them with LAMMPS and some using Material studio

I am wondering what is the pros and cons of each.

Thanks

The School of Civil and Environmental Engineering invites applications for two tenure-track faculty positions in structural engineering/mechanics/materials (SEMM). Candidates at all ranks are sought with expertise in one or more of the following areas: (1) computational/solid mechanics; (2) infrastructure materials. The expected starting date is August, 2011.

Fatigue

finite element modeling

Dear all,

I would like to ask you, how is it possible to simulate fatigue in Abaqus. I have created my loading. But if I run it as it is it will never reach a critical value, so you could say there is no damage evolution. Is it the only way is to apply some type of hysteresis loop evolution and say that after some cycles the hysteresis loop changes?

Any advice is more than welcome!

Regards,

Panos

Unit cell modeling using Abaqus submodeling

Micromechanical modeling

Hi,

I was going though papers related to micromechanical modeling of composites using unit cell approach. Usually in this procedure, a unit cell is isolated from the material and to ensure the compatabilty of the unit cell boundary, periodic boundary conditions are applied.

To ensure the compatabilty of the boundary and to apply loads, can we use submodeling techniques available in ABAQUS.

Thank you

Regards
