Chiara Modenese posted a new comment: @Klaus Yes, you are absolutely right and you refer to an excellent reference (worth reading it for those interested in conctact models). However, sometimes an analytical relationship is not possible to derive, such as in the HM model. @Bruno At present I am not able to commit that part of the code but if somebody follows my instruction it should be quick to do it. All, In my experience is not so critical to avoid tensile stresses due to viscous damping as I have always found them to be negligible but it is a good practice to neglect them entirely if possible. It is more of an issue if we are modelling cohesive particles, as there you expect the cohesion to match with your physical input.
