Actually, this question has been discussed so many times in the past years... but I can't find a clear and concise answer in the list or in the FAQ. "Young" has different meaning for different functors, which doesn't help consistency: 1- In CundallStrack, it is (proportional to, with proportionality factor of the order of 1) Young's modulus of the packing. 2- In HM, it is Young's modulus of the solid phase. 3- In ConcretePM, it is the directional Young modulus of the contact bond.
For Poisson, it is the same problem: 1- Correlated with packing's Poisson, 2- Poisson of the solid phase, 3- not used (correct?) For renaming Poisson, I introduced https://yade-dem.org/doc/yade.wrapper.html?highlight=ksdiv#yade.wrapper.TriaxialTest.sphereKsDivKn But at that time there were no HM-type laws... Now, I'm open to suggestions for renaming, but I can't find better names that would be relevant simultaneously for 1, 2 and 3. At least, the documentation tells what each functor is doing with Young and Poisson. I added something in the FAQ: https://yade-dem.org/wiki/FAQ#What_is_.22Young.22_and_.22Poisson.22_in_ElastMat_material.3F > I just want to simulate frictional elastic contacts for the moment, so it > seems appropriate. It's not really the contact law I want to check here for > my work. > Be careful Benoit... this a bit like "I don't care the equations, I just need the result": nonsense. Think twice before choosing a contact law.
