Mechanical constraint which prevents penetration between two bodies
In contact mechanics, the term unilateral contact, also called unilateral constraint, denotes a mechanical constraint which prevents penetration between two rigid/flexible bodies.
Constraints of this kind are omnipresent in non-smooth multibody dynamics applications, such as granular flows,[1] legged robot, vehicle dynamics, particle damping, imperfect joints,[2] or rocket landings. In these applications, the unilateral constraints result in impacts happening, therefore requiring suitable methods to deal with such constraints.
