In this presentation, a novel implicit impact model between spherical rigid bodies applied toi) subjected to multiple impact collisions.ii) three dimensional movements.iii)sliding, rolling and spinning friction effects.iv) fulfills exactly bilateral and unilateral constraints at position and velocity levels.We applied the element to:a three-dimensional spherical joint with lubrication.the impact analysis in a pool/billiard game.a ball-bearing element that is part of a crank rod mechanism.
