Ageing of Polymer Frictional Interfaces: The Role of Quantity and Quality of Contact Open
When two objects are in contact, the force necessary for one to start sliding over the other is larger than the force necessary to keep the sliding motion going. This difference between static and dynamic friction is thought to result from…
