Hi,
I am working on a coupled fluid structure problem , precisley on the elasto-acoustic mode, and i want to make sure that abaqus work with my matrix (stiffness and mass matrix) that i have made by fortran and at the same time i continu using abaqus element to mesh my model,
Any suggestion would be very appreciated
Thanks in advance
Regards
Lamia
hai iam syed; Iam doing one experimental problem of 3 point bend specimen, i want to now how to use cohesive element at crack tip region in abaqus fracture modeling, plz any body help me in solving fracture problem in abaqus
I would like to call your attention to a special Issue on "Polymer Nanocomposite Processing, Characterization, and Applications" scheduled to be published in the Journal of Nanomaterials in May 2010. The Call for Papers can also be viewed at the journal website at http://www.hindawi.com/journals/jnm/si/pnca.htm. The deadline for manuscript submission is November 1.

The physical basis of material
properties like Young's modulus can be understood by examining
materials on the atomic scale. There are two main things that influence
the value of the modulus:
1.) The atomic microstructure
2.) The interatomic bonds.

It is well known that the wall-to-wall interactions play a great part in the deformation of MWCNTs. At the first glance, I thought the pressures, duing to van der Waal interaction, on the inner tube and out tube should be proportional to their radii inversely, because this interaction is a kind of action and reaction. BUT actually it is not the case, as illuminated in our paper published in APL, although this two pressures are both functions of the radii, they are not inversely proportional to the radii.
As we know, lattice boltzmann method is one method to solve the fluid problems. and the primary work to use this method is give the corrected "boundary conditon"__pressure conditions and velocity conditions.
To general problems, the PC and VC for 2D/3D problems has been obtained by some scientists(eg.D3Q19,D2q9 ...model).
But to the lowest scale problems, the "force" fields is complexed and the traditional PC/VC is not suit for this kind of problems.
My opinion:
