I thought the mechanics community would be interested in the course notes of
Prof. K. J. Bathe on "Finite Element Analysis of Solids and Fluids". This
course was taught at MIT and now is available freely through MIT Open
CourseWare website:
Enjoy!
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.
Does anyone know anything about the life of V. V. Novozhilov, author of "Foundations of Nonlinear Theory of Elasticity"? Is he still living? Did he ever leave Leningrad?
Hello everyone
I need modeshapes for a tapered beam, so I am using Ansys. By going through the tutorials I found that a beam can be modeled by creating a line and meshing it using Beam elements and assigning real constants. How can I use the beam elements for a tapered beam where the real constants are not constant. I tried to use tapered beam element but is of no use as it the created all elements of same real constants creating a profile similar to a hack saw.
Can anyone please help me how to mesh a tapered beam.

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.
A post-doc researcher position is available from Sept 2009. Please contact Prof. John Wen at the Univerity of Waterloo. (jzwen [at] uwaterloo.ca (jzwen[at]uwaterloo[dot]ca))
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:
