FEM of carbon nanotube in resin
I am pretty new to FEM, but want to try to simulate the behavior of carbon nanotubes reinforced resin. I read another thread about carbon fibre in resin, so can I do similar setup for nanotubes? is it possible? or I have to use bulk approximations for many nano-sized tube? Thanks.
The simulation would be very basic, tension, compression... to be compared with DMA data.
So my following questions are:
If I can use direct nanotube in resin, I plan use a solid (or a shell) with interconnected links inside. Do you have any suggestions to generate a lot of interconnected links in an efficient way?
Or I have to use bulk approximations? Or it is not even possible to simulate such different sized materials together?
Thanks a lot!
How are you planning to represent the nanotubes? I did not quite understand your description about the interconnected links.
How many nanotubes do you wan to model?
How long are your nanotubes?
How big computer do you have?
The nanotubes will be a tube/cylinder of 2nm diameter, ~100nm length. The interconnected structure can be assumed either like honeycomb or tetrahedron, and if I can compare with the randomly interconnected structure, it will be wonderful.
I have modelled severl cases with molecular simulations in liquid environment (not good for solid like resin), for example 250 tube in a 300nm cube or about 10000 tubes/um^3. (Yes thats quite dense!)
I have access to a supercomputer and a cluster (for parellel) server.
With that computer power you should be able to create a reasonable micromechanicsl model that is representing the composite structure. Often is it useful to use repeated boundary conditions in order to simulate an infinite medium.
Best of luck,
