Publikováno v: Wear. :322-333

Frictional work dissipated into a pair of bodies in contact can lead to the generation of high temperatures at the interface. For extreme conditions, knowledge of such temperatures is indispensable for predicting material damage. Friction experiments

Publikováno v: Tribology International. 77:86-96

A model has been developed to study dry friction for a steel tribopair for a large range of sliding velocity. From the topology of two parts in contact, a true contact surface is defined as a set of asperities. Each adhesive junction is associated to
