Local defects in cylindrical roller (CR) bearings usually occur on the contact surfaces. The
ideal sharp-edged rectangular defect models given by the previous works are almost …

In cryogenic environments, it is not possible to apply oil or grease to ball bearings, owing to
the extreme temperature conditions. Thus, polytetrafluoroethylene (PTFE) cages are used as …

The present contribution deals with an investigation of the halo approach to simulate cracks
initiation and propagation in homogeneous and heterogeneous materials by Discrete …

The present paper deals with a novel method to predict the effective elastic behavior of
heterogeneous continuous materials using discrete element method. This work uses a …

A numerical approach makes electrical measurements in a rotating ball bearing, in order to
characterize the loading state of the bearing and to detect any defects. The ball bearing is …

This paper presents an original approach using Discrete Element Method (DEM) for
predicting the mechanical behavior of a bearing considering rigid and elastic housing. The …

The present paper deals with an original 2D modeling of mechanical state of ball bearings in
dynamic mode using the Discrete Element Method (DEM). An electromechanical coupling is …

This study presents an electro-mechanical contact model to investigate the electrical
response within a particulate system under mechanical loading. The model considers the …

We report a study about the electrical response from a sliding contact made of a silver-
graphite brush and a brass ring. This study focuses specifically on the voltage variations due …

In this article, the estimation of different defect sizes present on the outer race of taper roller
bearing confirms the effectiveness of the applied method for different vibration signals …
