... at this interface during the dry cutting of an AISI1045 steel with TiN coated carbide tools. A new tribometer, based on a modified pin-on-ring system, has been used in order to reach relevant values of pressures, temperatures, and sliding velocities. Additionally a 3D Arbitrary Lagrangian Eulerian model (A.L.E...

... approach, which considers the first body as rigid, are performed in terms of macroscopic friction coefficient and velocity and stress profiles. To close Eq. 4 , it is necessary to define the relation between u and r given by the interaction law. This can represent a unilateral contact, an elastic...

... is related to friction at the contact interface. Dimensionless solutions are obtained for maximum temperature rise, maximum contact force, maximum contact area, and maximum penetration as a function of dimensionless vertical initial velocity of the sphere. It is observed that transient thermomechanical...

...Jiaxin Zhao, Graduate Student; Farshid Sadeghi, Professor In this paper, an isothermal study of the shut down process of elastohydrodynamic lubrication under a constant load is performed. The surface mean velocity is decreased linearly from the initial steady state value to zero. The details...
