Darcy-Weisbach friction factor at the nanoscale: From atomistic calculations to continuum models
(2017)Amodification of the Darcy-Weisbach friction factor applicable to nanoscale liquid transport processes is proposed. Non-equilibrium molecular dynamics simulations allowus to access the atomic behaviour of liquids moving ... -
Dependence of friction coefficient on the resolution of asperities in metallic rough surfaces under cyclic loading
(2017)In this paper the friction mechanism that is developed between metallic rough interfaces with irregularities of different scales, submitted to cyclic loading is studied. The main purpose of the paper is to investigate how ... -
Friction factor in nanochannel flows
(2016)Non-equilibrium molecular dynamics simulations are employed in order to access the detailed atomic behavior of fluids moving in nanochannels and to quantify the associated energy dissipation. Nanochannels of various degrees ... -
Microstructural and mechanical characterization of solidified austenitic stainless steels
(2017)Among the family of stainless steels, cast austenitic stainless steels (CASSs) are preferably used due to their high mechanical properties and corrosion resistance. These steels owe their properties to their microstructural ... -
Phenomenological investigation of cutting oils: Antifriction and antiwear behaviour at low contact temperatures
(2001)The basic reason for the use of cutting fluids in machining processes is to increase cutting tool life and to decrease machining costs. An experimental simulation of tribological processes representing rear cutting tool ... -
Solution of nonmonotone friction unilateral contact problems within a neural network environment
(2002)A neural network approach for dealing with the solution of frictional contact problems is proposed. Such an approach permits the rational treatment of the aforementioned limit states. In particular, discretizing the structure ... -
Surface anisotropy for monitoring the wear of IC engine cylinders
(2004)The present work proposes a methodology for monitoring the wear of internal combustion engine cylinders. This could be useful in calculating the time at which maintenance should be done on such a tribosystem or in determining ... -
Tribological coatings for aerospace applications and the case of WC-Co plasma spray coatings
(2009)Friction and wear requirements in aerospace systems are dictated by life limiting problems. One challenge is the broad range of contact stresses and sliding speeds for various movable devices. Another challenge is the ...
