The prediction of wheel/rail rolling contact fatigue (RCF) crack initiation during railway
operations is an important task. Since RCF crack evolution is influenced by many factors, its …

Wear and contact fatigue are the main problems that reduce the durability of the rail and
wheels. Pearlitic and bainitic microstructures have been studied over the years to obtain …

Management of wheel-rail contact is of great importance for railways. It is essential to
understand the tribology of railway materials to maximize productivity and reduce …

The paper presents a new type of experiment focused on investigation of the influence of
mean stress and stress amplitude on steady state ratcheting realized in ST52 steel at the …

The prediction of wheel-rail rolling contact fatigue (RCF) crack initiation is a critical task in
rail operation, particularly when material surface defects are present at the wheel-rail …

In order to examine the effect of rolling speed on rolling contact fatigue (RCF) of wheel steel,
dry-wet rolling/sliding tests were carried out at varied rolling speeds. Wear loss, friction …

Preventive and corrective maintenance of the different components of rolling stock is
mandatory to guarantee the safety of passengers and workers when using rail transport …

Brazilian heavy-haul railway companies have drawn extensive research in the last years for
developing solutions that can make the operation in this area more efficient and safer, such …

The susceptibility of railway wheels to wear and rolling contact fatigue damage is influenced
by the properties of the wheel material. These are influenced by the steel composition …

In the present study, thermomechanical cracking of railway wheel treads is studied by full-
scale brake rig tests and finite element simulations. The main goal of the paper is to perform …
