Permanent indentation characterization for low-velocity impact modelling using three-point bending test [PDF]

open access: yes, 2014
This paper deals with the origin of permanent indentation in composite laminates subjected to low-velocity impact. The three-point bending test is used to exhibit a non-closure of matrix crack which is assumed as a cause of permanent indentation ...

Investigation into the effect of common factors on rolling resistance of belt conveyor

open access: yesAdvances in Mechanical Engineering, 2015
Since indentation rolling resistance accounts for the major part of total resistance of belt conveyor, it is important to compute it using a proper method during the design and application study of the belt conveyor.

Evaluation of rolling contact fatigue behaviour of bearing steel subjected to shot peening in a contaminated lubrication

open access: yesNihon Kikai Gakkai ronbunshu, 2017
In this study, the effect of shot peening on rolling contact fatigue life of bearing steel was investigated under contaminated lubrication. Shot peening was carried out on bearing steel SUJ2 specimens. Peened specimens were polished to remove the dimples

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

open access: yesAdvanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...
