    • Fatigue and fracture behavior of pearlitic Grade 900A steel used in railway applications 

      Christodoulou P.I., Kermanidis A.T., Haidemenopoulos G.N. (2016)
      In overloaded railway networks, rail surface defects developed under rolling contact fatigue (RCF) if left untreated, may propagate to the bulk of the rail and become critical for its structural integrity. To avoid critical ...

    • Rolling contact fatigue cracking in rails subjected to in-service loading 

      Haidemenopoulos G.N., Sarafoglou P.I., Christopoulos P., Zervaki A.D. (2016)
      Rolling contact fatigue (RCF) is one of the most important failure mechanisms in rails with significant cost- and safety-related implications on the operation of railway systems. In this work, a metallurgical analysis of ...

    • Rolling contact fatigue of rails 

      Haidemenopoulos, G. N.; Zervaki, A. D.; Giannakopoulos, A. (2013)
      Rolling contact fatigue (RCF) has been of increasing concern in the recent years regarding the safe operation of high-speed railway track with high traffic intensity. The present paper summarizes the results of an on-going ...

    • Visualization of the Rolling Contact Fatigue Cracks in Rail Tracks with a Magnetooptical Sensor 

      Chotzoglou A., Pissas M., Zervaki A.D., Haidemenopoulos G.N., Pissas T. (2019)
      The rolling contact fatigue cracks (RCF), produced at the surface of the rail tracks, can be detected using a magnetooptical (MO) sensor. Rail tracks are carbon steels with pearlite microstructure. This microstructure has ...
