Modelling nano scale in Abaqus

Modelling nano scale in Abaqus

Modelling nano scale in Abaqus

(OP)
Hello all,

Has anyone had any exeperience modelling nano sized structures in abaqus, is it possible? Has anyone seen any exmaples out there of this?

Thanks

RE: Modelling nano scale in Abaqus

What aspect of 'nano-scale' are you trying to capture? If its just the size then thats easy as Abaqus does not have a fixed size scale. I've modelled metals at the micro-scale using Abaqus, using crystal plasticity theory to represent the effects of atomic slip. Never nano-scale though. Would you have to model individual atomic interactions?

RE: Modelling nano scale in Abaqus

In my opinion, continuum FE formulations are not very useful at nano-scale. However, if you are interested in modeling inter-atomic interactions using user-defined "structural-like" elements you might be interested in the user subroutine UEL.
I think currently researchers are interested in multi-scale simulations where continuum FE formulations are coupled with molecular dynamics approaches.
