Numerical and analytical modeling of orthogonal cutting : The link between local variables and global contact characteristics [PDF]

, 2011
The response of the tool–chip interface is characterized in the orthogonal cutting process by numerical and analytical means and compared to experimental results. We study the link between local parameters (chip temperature, sliding friction coefficient,

Coarse-grained model for spring friction study of micron-scale iron by smoothed particle hydrodynamics

, 2018
The paper constructs a coarse-grained model to investigate dry sliding friction of the body-centered-cubic Fe micron-scale system by smoothed particle hydrodynamics simulations and examines influences of the spring force on the characters of friction ...

Phenomenological contact line friction coefficient

Droplet
An important feature of contact line motion, as an irreversible process, is its dissipative nature, which can dominate the dynamics during the early stages of droplet spreading.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Methods of calculation of a friction coefficient: Application to the nanotubes

, 2003
In this work we develop theoretical and numerical methods of calculation of a dynamic friction coefficient. The theoretical method is based on an adiabatic approximation which allows us to express the dynamic friction coefficient in terms of the time ...

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

Advanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Frictional Characterization Of Grey Cast Iron Train Brake Block Using A Reduced Scale Dynamometer

Mekanika, 2022
The brake block is an important component that serves to slow down and stop the train. The safety of this transportation is very dependent on the reliability of this component.
