Rail-wheel Interaction and Its Influence on Rail and Wheels Wear
Procedia Manufacturing, 2019 Abstract Railway superstructure and the rolling stock form a complex mechanical system. Due to the interaction between the rolling stock and the rail, wears occur, both at the wheel profile, as on the rail. This wears generate interaction forces that accelerates the railway track deterioration.

Bending Fatigue Evaluation and Failure Modes of Ultra‐Thin Silicon Chips on Flexible Substrates
FlexTech, EarlyView.This study investigates the fatigue lifetime of 20‐μm‐thick chips under bending deformation. Three failure modes are identified: metal pad wearing, metal stress migration, and gold wire break. The underlying mechanisms are analyzed through micro‐scale characterization, and temperature effects on fatigue lifetime are explored.

Investigation on rolling sliding wear behavior of wheel steel by laser dispersed treatment
, 2014 To improve wear resistance of wheel steels under rolling-sliding wear conditions, a novel technique named laser dispersed treatment (LDT) was used by forming a regular scattered hardening pattern distributed on the surface of wheel disc, which can avoid ...

Study on the Evolution of Wheel Wear and Its Impact on Vehicle Dynamics of High-Speed Trains
, 2022 Wheel wear is one of the most critical factors affecting the vehicle performances and maintenance costs of railway vehicles. However, previous research has to ignore the initial wheel-rail profiles for the evolution of wheel wear.
