Dislocation in Tensile Test
« on: October 10, 2018, 10:29:44 AM »
hi every one,

How can i analyzes dislocation in "Tensile Test" for CNTs?

Hi bity,

I don't have much experience with carbon nanotubes, so can you explain how dislocations in a carbon nanotube are defined? That might increase your chances that I or others can help you.

With regard to the FCC, the CNT structure and the linear defect can be studed.(of course i think!)

Bity,
Ovito provides an analysis function (see here)  for identifying and tracking dislocation line defects. But it only works for 3D bulk crystals. It cannot be applied to sheet materials or CNTs for that matter.

However, Ovito provides a collection of general tools for analyzing simulations and visualizing defects. Perhaps they can be useful for your purposes. Right now we don't have a good idea what you want to do and how your simulation model looks. If you like, give us some more insight into your problem. Perhaps we can provide some hints how Ovito can be useful.
