Hello colleagues,

 Would anybody know good references on numerical integration of non-polynomial functions? It would be enough for me to obtain one-dimensional rules. Of course, it could have impact for XFEM applications, but for another, improved XFEM method that we are developing.

Note  that I am not talking about integrating singularities, but non-polynomial functions. Examples:

sqrt(x)

cos(x)

sin(x)

product of these.

Thanks for any help,

Stephane

Generation of open ends carbon nanotubes coordinates (atomic positions) is easy and the generation of cap for these carbon nanotubes is extremely difficult. Some of the half-fullerenes (C60, C240, C540…) fit as a cap for the armchair and zigzag nanotubes. NanotubeModeler  (http://www.jcrystal.com/products/wincnt/index.htm) software generates the carbon nanotubes with cap but they are limited to few armchair and zigzag configurations.

Hi, guys...

I am a Mechanical Engineer (newly graduated).

Can somebody tell me where I can find a very good PhD studentship in APPLIED MECHANICS (i.e. vibro-acoustics, control systems, vehicle dynamics, etc...) in Europe?

I'm getting crazy with that... I hope somebody can help me.

Hello All:

Hypersingular Integral Equation Method to 3D Crack in Fully Coupled Electromagnetothermoelastic Multiphase Composites

Hi,

I found in polymer books and some literatures that mechanical properties of polymer improve with the increase of their radius of gyration or end-to-end distance for a fixed molecular weight. I, however, could not find any experimental evidence or any physical explanation. 

It will be a great help to me if anyone refer me some literatures that explains the connection between these two parameters.

 Thanks,
