Creeplike Relaxation at the Interface between Rough Solids under Shear

We study the transient behaviour of a slider coupled to a loading spring, creeping its way to rest from a low velocity sliding state. Experimentally, a two-stages process is observed which is analyzed with reference to a previously discussed theoretical model for creeplike friction dynamics at the interface between solids.Nous étudions la relaxation du glissement continu vers le repos d'un patin entraîné élastiquement. Un processus en deux étapes est observé et analysé à l'aide d'un modèle théorique de frottement solide en régime de fluage interfacial
