I can guarantee you that it will not be the last time I post questions on this topic on the yade launchpad. For simple deformable bodies, my team and I will most likely use it a lot in the future as soon as I know exactly how to use it and managed to properly simulate correct beahviour of a simple body. š > Set the mass of its nodes. That's all. Alright, thanks. Just applying the correct node density to achieve the same total mass that I want it to have. Total node mass = wanted total mass. Got it! > I would say they are two alias for the same thing. Am I confused? have seen one or the other in different scripts? As far as I know they are multiple similar approaches in the āMore examplesā section of the yade documentation. Just to summarize: - Chained-cylinders - Cylinders (or cylinder-connections. The example I initially used to open this question thread.) - Grids - PFacet (although this uses creators and gridNodes and gridConnections and only adds the PFacet) Since I am a newbie, I am not yet able to tell what the exact differences are, but they are more or less used for the same things (I believe). > if cohesion is small you can get get plastic deformation of the beam Ah I see. So, it is kind of needed to apply resistance to pulling. As particles only āgenerateā a force when moving towards, but not when moving away from each other. Linear elastic behaviour is totally fine for my use for now. Letās see where the journey goes. > Bending is defined for interactions, based on the differential rotation of two nodes. It is not defined "per node". Since I had a look in the paper you linked: Is it correct to imagine the bending behaviour as a rotational spring like in figure 3 of [3]? This what I initially meant when I proposed the question on how the bending behaviour āin a nodeā is computed. As a node itself canāt bend it is somewhat clear that it needs to happen in the interactions as this links multiple nodes. > Effeindzourou PhD dissertation Nevertheless it is a good summary, thanks for the hint! > There is an old 2D version of the same thing described in [3] As in the question above this gave some basic insights (probably). So this is still of value. Thanks for the suggestion!
