Analytical model for predicting friction in line contacts

An Analytical Model for Alloyed Ohmic Contacts Using a Trilayer Transmission Line Model

A predictive analytical friction model from basic theories of interfaces, contacts and dislocations

Friction between crystalline bodies is described in a model that unifies elements of dislocation drag, contact mechanics, and interface theory. An analytic expression for the friction force between solids suggests that dislocation drag accounts for many of the observed phenomena related to solid–solid sliding. Included in this approach are strong arguments for agreement with friction dependence...

A complementarity-based rolling friction model for rigid contacts

In this work1 we introduce a complementaritybased rolling friction model to characterize dissipative phenomena at the interface between moving parts. Since the formulation is based on differential inclusions, the model fits well in the context of nonsmooth dynamics, and it does not require short integration timesteps. The method encompasses a rolling resistance limit for static cases, similar t...

Friction Laws for Elastic Nano-Scale Contacts

– The effect of surface curvature on the law relating frictional forces F with normal load L is investigated by molecular dynamics simulations as a function of surface symmetry, adhesion, and contamination. Curved, non-adhering, dry, commensurate surfaces show a linear dependency, F ∝ L, similar to dry flat commensurate or amorphous surfaces and macroscopic surfaces. In contrast, curved, non-ad...

Development of a New Dynamic Friction Model for Analytical Modeling of Elliptical Vibration Assisted Turning Process

A new dynamic friction model for modeling of elliptical vibration assisted turning (EVAT) was developed in this research. The periodic change of the friction force direction is known to be one of the most important causes of this phenomenon. In modeling of machining processes (including the EVAT process), static Coulomb friction model was employed by most of the researchers. Because of the peri...
