implementation of mass matrix and stiffness matrix in abaqus using external subroutine
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

hai how to use cohesive element in abaqus
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.
Change in Elastic Modulus with Plastic Deformation

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.

Simple calculation, Interesting result -- van der Waal interaction of DWCNT
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.
