strain analysis- liminate homogeneous deformation kye
« on: January 14, 2019, 04:42:04 PM »
Dear Experts,

I am really confused by atomic strain analysis modifier. I cannot understand whether should I activated" eliminate homogeneous deformation " key or not?!
why should we remove homogeneous deformation? I am modeling a particle impact in z direction to a substrate.

Sorry if the question is very stupid

Best wishes,
Bahman

Dear Bahman,

it depends on what you would like to study. If you want to visualize only the plastic contribution to the overall deformation e.g., then it makes sense to eliminate any macroscopic, homogeneous deformation of the simulation cell, see the documentation about the atomic strain modifier:
