... receding contacts, i.e., when stick, slip, and separation along the interface are permitted (i.e., partial slip contact conditions). Dundurs and Stippes [ 1 ] showed for frictionless elastic receding contacts that the reduction in contact area with normal load is non-continuous. With the application...

... from the full stick model, both the Coulomb friction model and the proposed model are partial slip models in nature. However, the Coulomb friction is more empirically determined with some arbitrary friction coefficient, whereas the proposed model is based on physics parameters. Furthermore, both...
