Single-walled carbon nanotubes (SWNTs) possess extraordinary electrical and mechanical properties, with many possible applications in electronics and materials science. Dense, horizonally aligned arrays of linearly configured SWNTs represent perhaps the most attractive and scalable way to implement this class of nanomaterial in practical systems. Recent work shows that templated growth of tubes on certain crystalline substrates (e.g. quartz) yields arrays with the necessary levels of perfection, as demonstrated by the formation of devices and full systems on quartz.

Hi

Any body working on microstructural modelling, here i want know how to construct Basic real microstructure to FE mesh ?? 

This is the second call for abstracts for the 22nd Annual Melosh Competition for the Best Student Paper on Finite Element Analysis.  Extended abstracts are due by January 8, 2010.   Details of the competition and submission procedure can be found here. 

Hi, everyone

Now I meet a problem, wish can obtain you help.

Now i do some research on multi-compose particle materials (eg. pharmaceutical science  materials)___predict the compressibility, compactibility, flow properties and  breakage behavior.

as we know, the molecular scale at 0.1-70nm scale and crystal growth process at 0.1-100nm scale, can i use the constitutive relationship at micro(=~um)/macro to analyze the performance and structure at this scale.

thanks !

Hi all,

 I´m traying to simulate a low-cycle fatigue crack growth in Abaqus 6.9 using xfem. My problem is to add the low cycle method to the xfem solution. 

I believe that the only current option for this would be to manually
create the loading curve and to do the analysis by a brute force
method but i may not be correct in this assumption however.

Please could someone explain a brief method.

i appreciate in advance.
