Passive Broadband Targeted Energy Transfers and Control of Self -Excited Vibrations
… experimentally. It is also revealed that the dry friction affects only the robustness of an instability suppression by changing the unstable trivial equilibrium into an equilibrium set. (Abstract shortened by UMI.).

A molecular dynamics study of the tribological properties of diamond like carbon
… wear resistance and very low coefficient of friction . We use molecular dynamics (MD) simulations with a reactive force field (ReaxFF) to study the friction and wear between DLC counterfaces, both in comparison to and in contact with steel counterfaces. We show that the tribological …

Structural-model experiments revealing bifurcation, instability and localization
… and divergence instabilities as related to dry friction. All the experiments have been performed at the Laboratory for Physical Modeling of Structures and Photoelasticity of the Department of Mechanical and Structural Engineering of the University of Trento.

Tribological behavior of unfilled and carbon fiber reinforced polyether ether ketone/polyether imide composites
The friction and wear of injection molded Poly(ether ether ketone) (PEEK) and Poly(ether imide) (PEI), PEEK/PEI blends with the weight compositions of 50/50 %, 70/30 %, and 85/15 %, with and without short carbon fibers were measured in a pin(52100 steel ball)-on-disk(polymer blend) configuration …

Low-impact friction materials for brake pads
State-of-the-art friction materials for applications in disc brake systems are constituted by composite materials, specifically formulated to ensure proper friction and wear performances, under the sliding contact conditions of braking events. The bases of typical friction compound formulations …

Non-smooth dynamics and sensitivity analysis of multibody systems with clearances and friction in differential variational inequality framework
… mechanical joints with clearances with dry friction. Since clearances are small compared to the dimensions of me chanical components, contact is assumed to be inelastic. Based on this assumption and the general non-smooth dynamics framework, parametric formulations are derived for …

Experimental Characterization and Modeling of Tire-Ice Interface
… film created by the heat generated due to the friction force. Next, the viscous friction coefficient at the contact patch is obtained. By using the thermal balance equation at the contact patch, dry friction is obtained. Knowing the friction coefficients for the dry and wet regions, the …
