Abrasion – abrasion
Wear mechanism of part A induced by a harder, rougher counterpart B.
Membership – membership
Wear mechanism on part A where particles of A are transferred to counterpart B.
Coulomb friction coefficient
Ratio of tangential force to normal force when two solid bodies are in relative motion.
Archard wear coefficient – Archard wear coefficient
Product of wear volume and Vickers hardness of the body divided by normal force and sliding length.
Elastic strain – elastic strain
Reversible deformation of a material induced by a low level of stress. In uniaxial tension, stress is the product of Young's modulus and relative elongation.
