Description changed to:
Hi all,
I've been trying to model a triaxial test using JCFpmMat. This is the
method I'm using now to apply cohesions:
...
for i in O.interactions:
if isinstance(O.bodies[i.id1].shape,Sphere) and
isinstance(O.bodies[i.id2].shape,Sphere):
i.phys.isCohesive = True
radmin=min(O.bodies[i.id1].shape.radius,O.bodies[i.id2].shape.radius)
i.phys.FnMax = normalAdhesion * 3.141593 * radmin * radmin
i.phys.FsMax = shearAdhesion * 3.141593 * radmin * radmin
...
This does not satisfy me because:
1. I can't visualize broken interactions in this way. At the end of the test,
the interactions that showed "isBroken" only make up about 5%
2. I can't remodel the result in the following paper:
http://www.sciencedirect.com/science/article/pii/S0022509612002268
I tried the "sandstone" parameters in Table 3. (value of "c" as
"normalAdhesion", and "t" as "shearAdhesion") And results didn't show up the
same.
I believe there is an alternative way to apply cohesion other than edit
the value of i.phys.FnMax. Is it true?
