Multi-scale analysis of the roughness effect on lubricated rough contact [PDF]

, 2014
Determining friction is as equally essential as determining the film thickness in the lubricated contact, and is an important research subject. Indeed, reduction of friction in the automotive industry is important for both the minimization of fuel ...

Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

Advanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

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.

The use of a non-classical friction law in finite-element analysis of contact problems

, 1983
Bibliography: leaves 82-84.In this thesis a description is given of the numerical treatment of contact problems in elasticity. Frictional effects on the contact surface are modelled by using a nonlocal, nonlinear friction law.

An augmented Lagrangian frictional contact formulation for nonsmooth multibody systems [PDF]

, 2017
This work presents a frictional contact formulation for the transient simulation of non-smooth dynamic mechanical systems composed of rigid bodies, kinematic joints and contact conditions. More precisely, we extend the non-smooth generalized-alpha scheme
