Study of elastoplastic contact of a spherical indenter with metals and solid lubricating coatings: Part 1. Critical loads

A method for the engineering calculation of the critical loads that govern the origination and development of plastic deformation during the contact of a spherical indenter has been proposed as applied to the friction of metals and solid lubricating coatings. The available approaches to the investigation of elastoplastic contact deformations have been verified using the finite element method. The effect of a low-modulus coating on the origination of plastic deformations of the base has been shown.
