Contact induced wear filtering and its influence on corrugation growth

, 2010
Recent research has suggested that the contact mechanics between the wheel and rail in railway systems may act as a geometric filter for promoting the growth of short pitch wear-type corrugations.

Unconventional Hysteretic Charge Filling in Moiré‐Reconstructed Helical Trilayer Graphene

Advanced Science, EarlyView.
In helical trilayer graphene, sequential twisting reconstructs the moiré landscape into periodic domains separated by aperiodic boundaries. Longitudinal transport reveals sweep‐direction‐dependent hysteresis, while the Hall response traces this behavior to hysteretic charge filling at the aperiodic boundaries.

Maintenance Method for Rail Corrugation Considering Wheel–Rail Interaction Force

Applied Sciences
Rail corrugation causes various problems such as a decrease in ride comfort due to aggravation of train noise and vibration, and an increase in the amount of track component maintenance due to the amplification of the track impact.
