Adhesive wear and particle emission: Numerical approach based on asperity-free formulation of Rabinowicz criterion

open access: yesFriction, 2018
In 1953 Archard formulated his general law of wear stating that the amount of worn material is proportional to the normal force and the sliding distance, and is inversely proportional to the hardness of the material.
