Hi Jan,
Yes, you are right, the interaction factor didn't make much difference on the
overall behavior of the model. Previously my model was packed by
randomDensePack function and it seemed a bit loose.
I try to manipulate the bond strength like the code I attached below so that
some of the bonds may broke at early stage. And the cracks do appear earlier
but still the shape of stress-strain curve looks the same except the peak
stress & strain changes, and the relDuctivity seems only affect the hardening
process.
for i in O.interactions:
if strength_law == 0:
alpha=np.random.uniform(low,high)
elif strength_law == 1:
alpha=np.random.normal(1,std)
if alpha<0.01:
alpha = 0.01
i.phys.epsCrackOnset *= alpha
i.phys.undamagedCohesion *= alpha
