fatigue failure under cyclic loading using CPM

Asked by Weimin Song

Dear all,

          Does anyone do the research of the fatigue failure of concrete using CPM under cyclic loading, such as compression or tension load? Or is it available using CPM or other material types in YADE?

          Thanks!

Hello,
I have no experience with this kind of simulations and **in my opinion**
DEM is not the best approach..
What number of cycles would you like to simulate? I think the explicit
nature of DEM code would be the worst enemy here..
cheers

Thank you, Jan.

The cycles may be above 10000 times.

In this case, just try some "normal" simulation, get the length of time
step, how much real time does it take to compute it and extrapolate how
much would 10000 cycles take..
