hanzj is still having a problem:
dear prof.Bruno:
Thank you for your reply, and I understand what you mean mostly.sorry, I still
need your help as follows:
first,I have searched for what you recommend "assign the adhesion to the
different group", for example ,the question
"https://answers.launchpad.net/yade/+question/257929"[1] .is that what you
meant? and I would try to use it then and put my simple scripts here.
another question, if i am going to model the nano indentation process, and i
would like to use PFacet to model the hollow glass sphere, just not take into
account the splitting of the PFacet, it remains elastic or even plastic state.
and i use a spherical indenter to indent the composite made of glass sphere and
cement paste. I want to use DEM to model the nano indentation because my
material tends to be a particular problem, and I am going to model the loading
and unloading process and plot the diagram between the repulse force acting
on the spherical intender and the indenter displacement. there are other
authors use FEM to model the indentation like
http://www.sciencedirect.com/science/article/pii/S0040609016302966[2], are
there any other authors using DEM method or even YADE to do that? how to
calculate the repulse force acting on the indenter? The bonds between the
sphere and cement paste might be week enough to break down first and i have to
calibrate the adhesion between tw
o different materials, right? any ideas or recommendations?
If I have any logical problem and state that not correct, could you please let
me know, thank you.
looking forwards to your reply.
best regards
hanzj
