For your first question: go through the material under "Stabilization"


For your second question, if the energy dissipation ratio is high, the resultant stabilization force is high and hence will result in a stiffer response. We use these techniques (either energy dissipation factor or damping factor) to add a small numerical force to stabilize the simulation. This is not a physical force, but a numerical one. So ideally it should be as small as possible so that it doesn't change the physics of the problem. You can go through the material under "Controlling the Stabilization Force" to understand it further:


Hope this helps,
