Dependence of boundary lubrication on the misfit angle between the sliding surfaces

, 2010
Using molecular dynamics based on Langevin equations with a coordinate- and velocity-dependent damping coefficient, we study the frictional properties of a thin layer of "soft" lubricant (where the interaction within the lubricant is weaker than the ...

The contact dynamics method for granular media

, 2002
In this paper we review the simulation method of the non-smooth contact dynamics. This technique was designed to solve the unilateral and frictional contact problem for a large number of rigid bodies and has proved to be especially valuable in research ...

Frictional Effects in Biomimetic Scales Engagement

, 2015
Scales engagement can contribute significantly to nonlinear bending behavior of elastic substrates with rigid biomimetic scales. In this letter, we investigate the role of friction in modulating the nonlinearity that arises due to self-contact of scales ...

Finite element analysis of the thermal and thermo-mechanical coupling problems in the dry friction clutches using functionally graded material

Curved and Layered Structures
The friction clutch is an important machine part in the torque transmission system, where it is responsible for gently transmitting the power from the engine to the gearbox and damping the tensional vibration.

Evolution of swelling pressure of cohesive-frictional, rough and elasto-plastic granulates [PDF]

, 2010
The subject of this study is the modeling of the evolution of the swell-ing pressure of granulates with cohesive-frictional, rough and elasto-plastic “mi-croscopic” contact properties.

Solutions of contact problems by the assumed stress hybrid model [PDF]

A method was developed for contact problems which may be either frictional or frictionless and may involve extensive sliding between deformable bodies.

Formulation and Preparation for Numerical Evaluation of Linear Complementarity Systems in Dynamics [PDF]

, 2018
In this paper, we provide a full instruction on how to formulate and evaluate planar frictional contact problems in the spirit of non-smooth dynamics. By stating the equations of motion as an equality of measures, frictional contact reactions are taken ...

A Review of Tribological Behavior of Wire Ropes: Generation, Characteristics, Effects, and Protection

Lubricants
Steel wire ropes are key load-bearing components in systems such as mine hoisting, bridge cableways, elevators, and cranes, and frictional wear is among the earliest occurring and most easily accumulated form of damage.
